+Version 19.12.0
+===============
+
+Bugfixes
+********
+
+- Fix blueprint middleware application
+
+  Currently, any blueprint middleware registered, irrespective of which blueprint was used to do so, was
+  being applied to all of the routes created by the :code:`@app` and :code:`@blueprint` alike.
+
+  As part of this change, the blueprint based middleware application is enforced based on where they are
+  registered.
+
+  - If you register a middleware via :code:`@blueprint.middleware` then it will apply only to the routes defined by the blueprint.
+  - If you register a middleware via :code:`@blueprint_group.middleware` then it will apply to all blueprint based routes that are part of the group.
+  - If you define a middleware via :code:`@app.middleware` then it will be applied on all available routes (`#37 <https://github.com/huge-success/sanic/issues/37>`__)
+- Fix `url_for` behavior with missing SERVER_NAME
+
+  If the `SERVER_NAME` was missing in the `app.config` entity, the `url_for` on the `request` and  `app` were failing
+  due to an `AttributeError`. This fix makes the availability of `SERVER_NAME` on our `app.config` an optional behavior. (`#1707 <https://github.com/huge-success/sanic/issues/1707>`__)
+
+
+Improved Documentation
+**********************
+
+- Move docs from RST to MD
+
+  Moved all docs from markdown to restructured text like the rest of the docs to unify the scheme and make it easier in
+  the future to update documentation. (`#1691 <https://github.com/huge-success/sanic/issues/1691>`__)
+- Fix documentation for `get` and `getlist` of the `request.args`
+
+  Add additional example for showing the usage of `getlist` and fix the documentation string for `request.args` behavior (`#1704 <https://github.com/huge-success/sanic/issues/1704>`__)
+
+
+Version 19.6.3
+==============
+
+Features
+********
+
+- Enable Towncrier Support
+
+  As part of this feature, `towncrier` is being introduced as a mechanism to partially  automate the process
+  of generating and managing change logs as part of each of pull requests. (`#1631 <https://github.com/huge-success/sanic/issues/1631>`__)
+
+
+Improved Documentation
+**********************
+
+- Documentation infrastructure changes
+
+  - Enable having a single common `CHANGELOG` file for both GitHub page and documentation
+  - Fix Sphinix deprecation warnings
+  - Fix documentation warnings due to invalid `rst` indentation
+  - Enable common contribution guidelines file across GitHub and documentation via `CONTRIBUTING.rst` (`#1631 <https://github.com/huge-success/sanic/issues/1631>`__)

+    Fix graceful shutdown.
+
+  * 
+    `#1594 <https://github.com/huge-success/sanic/pull/1594>`_
+    Strict Slashes behavior fix
+
+Deprecations and Removals
+*************************
+
+  *
+    `#1544 <https://github.com/huge-success/sanic/pull/1544>`_
+    Drop dependency on distutil
+
+  * 
+    `#1562 <https://github.com/huge-success/sanic/pull/1562>`_
+    Drop support for Python 3.5
+
+  * 
+    `#1568 <https://github.com/huge-success/sanic/pull/1568>`_
+    Deprecate route removal.
+
+.. warning::
+    Sanic will not support Python 3.5 from version 19.6 and forward. However,
+    version 18.12LTS will have its support period extended thru December 2020, and
+    therefore passing Python's official support version 3.5, which is set to expire
+    in September 2020.
+
+
+Version 19.3
+============
+
+Features
+********
+
+  * 
+    `#1497 <https://github.com/huge-success/sanic/pull/1497>`_
+    Add support for zero-length and RFC 5987 encoded filename for
+    multipart/form-data requests.
+
+  * 
+    `#1484 <https://github.com/huge-success/sanic/pull/1484>`_
+    The type of ``expires`` attribute of ``sanic.cookies.Cookie`` is now
+    enforced to be of type ``datetime``.
+
+  * 
+    `#1482 <https://github.com/huge-success/sanic/pull/1482>`_
+    Add support for the ``stream`` parameter of ``sanic.Sanic.add_route()``
+    available to ``sanic.Blueprint.add_route()``.
+
+  * 
+    `#1481 <https://github.com/huge-success/sanic/pull/1481>`_
+    Accept negative values for route parameters with type ``int`` or ``number``.
+
+  * 
+    `#1476 <https://github.com/huge-success/sanic/pull/1476>`_
+    Deprecated the use of ``sanic.request.Request.raw_args`` - it has a
+    fundamental flaw in which is drops repeated query string parameters.
+    Added ``sanic.request.Request.query_args`` as a replacement for the
+    original use-case.
+
+  * 
+    `#1472 <https://github.com/huge-success/sanic/pull/1472>`_
+    Remove an unwanted ``None`` check in Request class ``repr`` implementation.
+    This changes the default ``repr`` of a Request from ``<Request>`` to
+    ``<Request: None />``
+
+  * 
+    `#1470 <https://github.com/huge-success/sanic/pull/1470>`_
+    Added 2 new parameters to ``sanic.app.Sanic.create_server``\ :
+
+
+    * ``return_asyncio_server`` - whether to return an asyncio.Server.
+    * ``asyncio_server_kwargs`` - kwargs to pass to ``loop.create_server`` for
+      the event loop that sanic is using.
+
+    This is a breaking change.
+
+  * 
+    `#1499 <https://github.com/huge-success/sanic/pull/1499>`_
+    Added a set of test cases that test and benchmark route resolution.
+
+  * 
+    `#1457 <https://github.com/huge-success/sanic/pull/1457>`_
+    The type of the ``"max-age"`` value in a ``sanic.cookies.Cookie`` is now
+    enforced to be an integer. Non-integer values are replaced with ``0``.
+
+  * 
+    `#1445 <https://github.com/huge-success/sanic/pull/1445>`_
+    Added the ``endpoint`` attribute to an incoming ``request``\ , containing the
+    name of the handler function.
+
+  * 
+    `#1423 <https://github.com/huge-success/sanic/pull/1423>`_
+    Improved request streaming. ``request.stream`` is now a bounded-size buffer
+    instead of an unbounded queue. Callers must now call
+    ``await request.stream.read()`` instead of ``await request.stream.get()``
+    to read each portion of the body.
+
+    This is a breaking change.
+
+Bugfixes
+********
+
+
+  * 
+    `#1502 <https://github.com/huge-success/sanic/pull/1502>`_
+    Sanic was prefetching ``time.time()`` and updating it once per second to
+    avoid excessive ``time.time()`` calls. The implementation was observed to
+    cause memory leaks in some cases. The benefit of the prefetch appeared
+    to negligible, so this has been removed. Fixes
+    `#1500 <https://github.com/huge-success/sanic/pull/1500>`_
+
+  * 
+    `#1501 <https://github.com/huge-success/sanic/pull/1501>`_
+    Fix a bug in the auto-reloader when the process was launched as a module
+    i.e. ``python -m init0.mod1`` where the sanic server is started
+    in ``init0/mod1.py`` with ``debug`` enabled and imports another module in
+    ``init0``.
+
+  * 
+    `#1376 <https://github.com/huge-success/sanic/pull/1376>`_
+    Allow sanic test client to bind to a random port by specifying
+    ``port=None`` when constructing a ``SanicTestClient``
+
+  * 
+    `#1399 <https://github.com/huge-success/sanic/pull/1399>`_
+    Added the ability to specify middleware on a blueprint group, so that all
+    routes produced from the blueprints in the group have the middleware
+    applied.
+
+  * 
+    `#1442 <https://github.com/huge-success/sanic/pull/1442>`_
+    Allow the the use the ``SANIC_ACCESS_LOG`` environment variable to
+    enable/disable the access log when not explicitly passed to ``app.run()``.
+    This allows the access log to be disabled for example when running via
+    gunicorn.

+
+Version 18.12
+=============
+
+18.12.0
+*******
+
+* 
+  Changes:
+
+
+  * Improved codebase test coverage from 81% to 91%.
+  * Added stream_large_files and host examples in static_file document
+  * Added methods to append and finish body content on Request (#1379)
+  * Integrated with .appveyor.yml for windows ci support
+  * Added documentation for AF_INET6 and AF_UNIX socket usage

+  * Cancel task when connection_lost
+  * Simplify request ip and port retrieval logic
+  * Handle config error in load config file.
+  * Integrate with codecov for CI
+  * Add missed documentation for config section.
+  * Deprecate Handler.log
+  * Pinned httptools requirement to version 0.0.10+
+
+* 
+  Fixes:
+
+
+  * Fix ``remove_entity_headers`` helper function (#1415)
+  * Fix TypeError when use Blueprint.group() to group blueprint with default url_prefix, Use os.path.normpath to avoid invalid url_prefix like api//v1
+    f8a6af1 Rename the ``http`` module to ``helpers`` to prevent conflicts with the built-in Python http library (fixes #1323)
+  * Fix unittests on windows
+  * Fix Namespacing of sanic logger
+  * Fix missing quotes in decorator example
+  * Fix redirect with quoted param
+  * Fix doc for latest blueprint code

-# Contributing
-
-Thank you for your interest! Sanic is always looking for contributors. If you
-don't feel comfortable contributing code, adding docstrings to the source files
-is very appreciated.
-
-We are committed to providing a friendly, safe and welcoming environment for all,
-regardless of gender, sexual orientation, disability, ethnicity, religion,
-or similar personal characteristic.
-Our [code of conduct](./CONDUCT.md) sets the standards for behavior.
-
-## Installation
-
-To develop on sanic (and mainly to just run the tests) it is highly recommend to
-install from sources.
-
-So assume you have already cloned the repo and are in the working directory with
-a virtual environment already set up, then run:
-
-```bash
-python setup.py develop && pip install -r requirements-dev.txt
-```
-
-## Running tests
-
-To run the tests for sanic it is recommended to use tox like so:
-
-```bash
-tox
-```
-
-See it's that simple!
-
-## Pull requests!
-
-So the pull request approval rules are pretty simple:
-1. All pull requests must pass unit tests.
-2. All pull requests must be reviewed and approved by at least
-one current collaborator on the project.
-3. All pull requests must pass flake8 checks.
-4. All pull requests must be consistent with the existing code.
-5. If you decide to remove/change anything from any common interface
-a deprecation message should accompany it.
-6. If you implement a new feature you should have at least one unit
-test to accompany it.
-7. An example must be one of the following:
-  * Example of how to use Sanic
-  * Example of how to use Sanic extensions
-  * Example of how to use Sanic and asynchronous library
-
-## Documentation
-
-Sanic's documentation is built
-using [sphinx](http://www.sphinx-doc.org/en/1.5.1/). Guides are written in
-Markdown and can be found in the `docs` folder, while the module reference is
-automatically generated using `sphinx-apidoc`.
-
-To generate the documentation from scratch:
-
-```bash
-sphinx-apidoc -fo docs/_api/ sanic
-sphinx-build -b html docs docs/_build
-```
-
-The HTML documentation will be created in the `docs/_build` folder.
-
-## Warning
-
-One of the main goals of Sanic is speed. Code that lowers the performance of
-Sanic without significant gains in usability, security, or features may not be
-merged. Please don't let this intimidate you! If you have any concerns about an
-idea, open an issue for discussion and help.

+
+Installation
+------------
+
+To develop on sanic (and mainly to just run the tests) it is highly recommend to
+install from sources.
+
+So assume you have already cloned the repo and are in the working directory with
+a virtual environment already set up, then run:
+
+.. code-block:: bash
+
+   pip3 install -e . ".[dev]"
+
+Dependency Changes
+------------------
+
+``Sanic`` doesn't use ``requirements*.txt`` files to manage any kind of dependencies related to it in order to simplify the
+effort required in managing the dependencies. Please make sure you have read and understood the following section of
+the document that explains the way ``sanic`` manages dependencies inside the ``setup.py`` file.
+
+.. list-table::
+   :header-rows: 1
+
+   * - Dependency Type
+     - Usage
+     - Installation
+   * - requirements
+     - Bare minimum dependencies required for sanic to function
+     - ``pip3 install -e .``
+   * - tests_require / extras_require['test']
+     - Dependencies required to run the Unit Tests for ``sanic``
+     - ``pip3 install -e '.[test]'``
+   * - extras_require['dev']
+     - Additional Development requirements to add contributing
+     - ``pip3 install -e '.[dev]'``
+   * - extras_require['docs']
+     - Dependencies required to enable building and enhancing sanic documentation
+     - ``pip3 install -e '.[docs]'``
+
+
+Running all tests
+-----------------
+
+To run the tests for Sanic it is recommended to use tox like so:
+
+.. code-block:: bash
+
+   tox
+
+See it's that simple!
+
+``tox.ini`` contains different environments. Running ``tox`` without any arguments will
+run all unittests, perform lint and other checks.
+
+Run unittests
+-------------
+
+``tox`` environment -> ``[testenv]``
+
+To execute only unittests, run ``tox`` with environment like so:
+
+.. code-block:: bash
+
+   tox -e py36 -v -- tests/test_config.py
+   # or
+   tox -e py37 -v -- tests/test_config.py
+
+Run lint checks
+---------------
+
+``tox`` environment -> ``[testenv:lint]``
+
+Permform ``flake8``\ , ``black`` and ``isort`` checks.
+
+.. code-block:: bash
+
+   tox -e lint
+
+Run other checks
+----------------
+
+``tox`` environment -> ``[testenv:check]``
+
+Perform other checks.
+
+.. code-block:: bash
+
+   tox -e check
+
+Run Static Analysis
+-------------------
+
+``tox`` environment -> ``[testenv:security]``
+
+Perform static analysis security scan
+
+.. code-block:: bash
+
+   tox -e security
+
+Run Documentation sanity check
+------------------------------
+
+``tox`` environment -> ``[testenv:docs]``
+
+Perform sanity check on documentation
+
+.. code-block:: bash
+
+   tox -e docs
+
+
+Code Style
+----------
+
+To maintain the code consistency, Sanic uses following tools.
+
+
+#. `isort <https://github.com/timothycrosley/isort>`_
+#. `black <https://github.com/python/black>`_
+#. `flake8 <https://github.com/PyCQA/flake8>`_
+
+isort
+*****
+
+``isort`` sorts Python imports. It divides imports into three
+categories sorted each in alphabetical order.
+
+
+#. built-in
+#. third-party
+#. project-specific
+
+black
+*****
+
+``black`` is a Python code formatter.
+
+flake8
+******
+
+``flake8`` is a Python style guide that wraps following tools into one.
+
+
+#. PyFlakes
+#. pycodestyle
+#. Ned Batchelder's McCabe script
+
+``isort``\ , ``black`` and ``flake8`` checks are performed during ``tox`` lint checks.
+
+Refer `tox <https://tox.readthedocs.io/en/latest/index.html>`_ documentation for more details.
+
+Pull requests
+-------------
+
+So the pull request approval rules are pretty simple:
+
+#. All pull requests must have a changelog details associated with it.
+#. All pull requests must pass unit tests.
+#. All pull requests must be reviewed and approved by at least one current collaborator on the project.
+#. All pull requests must pass flake8 checks.
+#. All pull requests must be consistent with the existing code.
+#. If you decide to remove/change anything from any common interface a deprecation message should accompany it.
+#. If you implement a new feature you should have at least one unit test to accompany it.
+#. An example must be one of the following:
+
+   * Example of how to use Sanic
+   * Example of how to use Sanic extensions
+   * Example of how to use Sanic and asynchronous library
+
+
+Changelog
+---------
+
+It is mandatory to add documentation for Change log as part of your Pull request when you fix/contribute something
+to the ``sanic`` community. This will enable us in generating better and well defined change logs during the
+release which can aid community users in a great way.
+
+.. note::
+
+    Single line explaining the details of the PR in brief
+
+    Detailed description of what the PR is about and what changes or enhancements are being done.
+    No need to include examples or any other details here. But it is important that you provide
+    enough context here to let user understand what this change is all about and why it is being
+    introduced into the ``sanic`` codebase.
+
+    Make sure you leave an line space after the first line to make sure the document rendering is clean

+Sanic | Build fast. Run fast.
+=============================
 
-Sanic is a Flask-like Python 3.5+ web server that's written to go fast.  It's based on the work done by the amazing folks at magicstack, and was inspired by `this article <https://magic.io/blog/uvloop-blazing-fast-python-networking/>`_.
+.. start-badges
 
-On top of being Flask-like, Sanic supports async request handlers.  This means you can use the new shiny async/await syntax from Python 3.5, making your code non-blocking and speedy.
+.. list-table::
+    :stub-columns: 1
 
-Sanic is developed `on GitHub <https://github.com/huge-success/sanic/>`_. We also have `a community discussion board <https://community.sanicframework.org/>`_. Contributions are welcome!

+
+Sanic is a **Python 3.6+** web server and web framework that's written to go fast. It allows the usage of the ``async/await`` syntax added in Python 3.5, which makes your code non-blocking and speedy.
+
+`Source code on GitHub <https://github.com/huge-success/sanic/>`_ | `Help and discussion board <https://community.sanicframework.org/>`_. 
+
+The project is maintained by the community, for the community. **Contributions are welcome!**
+
+The goal of the project is to provide a simple way to get up and running a highly performant HTTP server that is easy to build, to expand, and ultimately to scale.
+
+Installation
+------------
+
+``pip3 install sanic``
+
+    Sanic makes use of ``uvloop`` and ``ujson`` to help with performance. If you do not want to use those packages, simply add an environmental variable ``SANIC_NO_UVLOOP=true`` or ``SANIC_NO_UJSON=true`` at install time.
+    
+    .. code:: shell
+    
+       $ export SANIC_NO_UVLOOP=true
+       $ export SANIC_NO_UJSON=true 
+       $ pip3 install --no-binary :all: sanic
+
+
+.. note::
+
+  If you are running on a clean install of Fedora 28 or above, please make sure you have the ``redhat-rpm-config`` package installed in case if you want to
+  use ``sanic`` with ``ujson`` dependency.
 
-If you have a project that utilizes Sanic make sure to comment on the `issue <https://github.com/huge-success/sanic/issues/396>`_ that we use to track those projects!

+Python 3.7 AsyncIO examples
+###########################
+
+With Python 3.7 AsyncIO got major update for the following types:
+
+ - asyncio.AbstractEventLoop
+ - asyncio.AbstractServer
+
+
+This example shows how to use sanic with Python 3.7, to be precise: how to retrieve an asyncio server instance:
+
+.. code:: python
+
+    import asyncio
+    import socket
+    import os
+
+    from sanic import Sanic
+    from sanic.response import json
+
+    app = Sanic(__name__)
+
+
+    @app.route("/")
+    async def test(request):
+        return json({"hello": "world"})
+
+
+    server_socket = '/tmp/sanic.sock'
+
+    sock = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
+
+    try:
+        os.remove(server_socket)
+    finally:
+        sock.bind(server_socket)
+
+    if __name__ == "__main__":
+        loop = asyncio.get_event_loop()
+        srv_coro = app.create_server(
+            sock=sock,
+            return_asyncio_server=True,

+                start_serving=False
+            )
+        )
+        srv = loop.run_until_complete(srv_coro)
+        try:
+            assert srv.is_serving() is False
+            loop.run_until_complete(srv.start_serving())
+            assert srv.is_serving() is True

+        except KeyboardInterrupt:
+            srv.close()
+            loop.close()
+
+
+Please note that uvloop does not support these features yet.

-# Blueprints
-
-Blueprints are objects that can be used for sub-routing within an application.
-Instead of adding routes to the application instance, blueprints define similar
-methods for adding routes, which are then registered with the application in a
-flexible and pluggable manner.
-
-Blueprints are especially useful for larger applications, where your
-application logic can be broken down into several groups or areas of
-responsibility.
-
-## My First Blueprint
-
-The following shows a very simple blueprint that registers a handler-function at
-the root `/` of your application.
-
-Suppose you save this file as `my_blueprint.py`, which can be imported into your
-main application later.
-
-```python
-from sanic.response import json
-from sanic import Blueprint
-
-bp = Blueprint('my_blueprint')
-
-@bp.route('/')
-async def bp_root(request):
-    return json({'my': 'blueprint'})
-
-```
-
-## Registering blueprints
-
-Blueprints must be registered with the application.
-
-```python
-from sanic import Sanic
-from my_blueprint import bp
-
-app = Sanic(__name__)
-app.blueprint(bp)
-
-app.run(host='0.0.0.0', port=8000, debug=True)
-```
-
-This will add the blueprint to the application and register any routes defined
-by that blueprint. In this example, the registered routes in the `app.router`
-will look like:
-
-```python
-[Route(handler=<function bp_root at 0x7f908382f9d8>, methods=frozenset({'GET'}), pattern=re.compile('^/$'), parameters=[], name='my_blueprint.bp_root', uri='/')]
-```
-
-## Blueprint groups and nesting
-
-Blueprints may also be registered as part of a list or tuple, where the registrar will recursively cycle through any sub-sequences of blueprints and register them accordingly. The `Blueprint.group` method is provided to simplify this process, allowing a 'mock' backend directory structure mimicking what's seen from the front end. Consider this (quite contrived) example:
-
-```
-api/
-├──content/
-│  ├──authors.py
-│  ├──static.py
-│  └──__init__.py
-├──info.py
-└──__init__.py
-app.py
-```
-
-Initialization of this app's blueprint hierarchy could go as follows:
-
-```python
-# api/content/authors.py
-from sanic import Blueprint
-
-authors = Blueprint('content_authors', url_prefix='/authors')
-```
-```python
-# api/content/static.py
-from sanic import Blueprint
-
-static = Blueprint('content_static', url_prefix='/static')
-```
-```python
-# api/content/__init__.py
-from sanic import Blueprint
-
-from .static import static
-from .authors import authors
-
-content = Blueprint.group(static, authors, url_prefix='/content')
-```
-```python
-# api/info.py
-from sanic import Blueprint
-
-info = Blueprint('info', url_prefix='/info')
-```
-```python
-# api/__init__.py
-from sanic import Blueprint
-
-from .content import content
-from .info import info
-
-api = Blueprint.group(content, info, url_prefix='/api')
-```
-
-And registering these blueprints in `app.py` can now be done like so:
-
-```python
-# app.py
-from sanic import Sanic
-
-from .api import api
-
-app = Sanic(__name__)
-
-app.blueprint(api)
-```
-
-## Using blueprints
-
-Blueprints have much the same functionality as an application instance.
-
-### WebSocket routes
-
-WebSocket handlers can be registered on a blueprint using the `@bp.websocket`
-decorator or `bp.add_websocket_route` method.
-
-### Middleware
-
-Using blueprints allows you to also register middleware globally.
-
-```python
-@bp.middleware
-async def print_on_request(request):
-	print("I am a spy")
-
-@bp.middleware('request')
-async def halt_request(request):
-	return text('I halted the request')
-
-@bp.middleware('response')
-async def halt_response(request, response):
-	return text('I halted the response')
-```
-
-### Exceptions
-
-Exceptions can be applied exclusively to blueprints globally.
-
-```python
-@bp.exception(NotFound)
-def ignore_404s(request, exception):
-	return text("Yep, I totally found the page: {}".format(request.url))
-```
-
-### Static files
-
-Static files can be served globally, under the blueprint prefix.
-
-```python
-
-# suppose bp.name == 'bp'
-
-bp.static('/web/path', '/folder/to/serve')
-# also you can pass name parameter to it for url_for
-bp.static('/web/path', '/folder/to/server', name='uploads')
-app.url_for('static', name='bp.uploads', filename='file.txt') == '/bp/web/path/file.txt'
-
-```
-
-## Start and stop
-
-Blueprints can run functions during the start and stop process of the server.
-If running in multiprocessor mode (more than 1 worker), these are triggered
-after the workers fork.
-
-Available events are:
-
-- `before_server_start`: Executed before the server begins to accept connections
-- `after_server_start`: Executed after the server begins to accept connections
-- `before_server_stop`: Executed before the server stops accepting connections
-- `after_server_stop`: Executed after the server is stopped and all requests are complete
-
-```python
-bp = Blueprint('my_blueprint')
-
-@bp.listener('before_server_start')
-async def setup_connection(app, loop):
-    global database
-    database = mysql.connect(host='127.0.0.1'...)
-
-@bp.listener('after_server_stop')
-async def close_connection(app, loop):
-    await database.close()
-```
-
-## Use-case: API versioning
-
-Blueprints can be very useful for API versioning, where one blueprint may point
-at `/v1/<routes>`, and another pointing at `/v2/<routes>`.
-
-When a blueprint is initialised, it can take an optional `url_prefix` argument,
-which will be prepended to all routes defined on the blueprint. This feature
-can be used to implement our API versioning scheme.
-
-```python
-# blueprints.py
-from sanic.response import text
-from sanic import Blueprint
-
-blueprint_v1 = Blueprint('v1', url_prefix='/v1')
-blueprint_v2 = Blueprint('v2', url_prefix='/v2')
-
-@blueprint_v1.route('/')
-async def api_v1_root(request):
-    return text('Welcome to version 1 of our documentation')
-
-@blueprint_v2.route('/')
-async def api_v2_root(request):
-    return text('Welcome to version 2 of our documentation')
-```
-
-When we register our blueprints on the app, the routes `/v1` and `/v2` will now
-point to the individual blueprints, which allows the creation of *sub-sites*
-for each API version.
-
-```python
-# main.py
-from sanic import Sanic
-from blueprints import blueprint_v1, blueprint_v2
-
-app = Sanic(__name__)
-app.blueprint(blueprint_v1, url_prefix='/v1')
-app.blueprint(blueprint_v2, url_prefix='/v2')
-
-app.run(host='0.0.0.0', port=8000, debug=True)
-```
-
-## URL Building with `url_for`
-
-If you wish to generate a URL for a route inside of a blueprint, remember that the endpoint name
-takes the format `<blueprint_name>.<handler_name>`. For example:
-
-```python
-@blueprint_v1.route('/')
-async def root(request):
-    url = request.app.url_for('v1.post_handler', post_id=5) # --> '/v1/post/5'
-    return redirect(url)
-
-
-@blueprint_v1.route('/post/<post_id>')
-async def post_handler(request, post_id):
-    return text('Post {} in Blueprint V1'.format(post_id))
-```

+
+Using Blueprints
+----------------
+
+Blueprints have almost the same functionality as an application instance.
+
+WebSocket routes
+~~~~~~~~~~~~~~~~
+
+WebSocket handlers can be registered on a blueprint using the `@bp.websocket`
+decorator or `bp.add_websocket_route` method.
+
+Blueprint Middleware
+~~~~~~~~~~~~~~~~~~~~
+
+Using blueprints allows you to also register middleware globally.
+
+.. code-block:: python
+
+    @bp.middleware
+    async def print_on_request(request):
+        print("I am a spy")
+
+    @bp.middleware('request')
+    async def halt_request(request):

+
+    @bp.middleware('response')
+    async def halt_response(request, response):
+        return text('I halted the response')
+
+
+Blueprint Group Middleware
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Using this middleware will ensure that you can apply a common middleware to all the blueprints that form the
+current blueprint group under consideration.
+
+.. code-block:: python
+
+    bp1 = Blueprint('bp1', url_prefix='/bp1')
+    bp2 = Blueprint('bp2', url_prefix='/bp2')
+
+    @bp1.middleware('request')
+    async def bp1_only_middleware(request):
+        print('applied on Blueprint : bp1 Only')
+
+    @bp1.route('/')
+    async def bp1_route(request):
+        return text('bp1')
+
+    @bp2.route('/<param>')
+    async def bp2_route(request, param):
+        return text(param)
+
+    group = Blueprint.group(bp1, bp2)
+
+    @group.middleware('request')
+    async def group_middleware(request):
+        print('common middleware applied for both bp1 and bp2')
+
+    # Register Blueprint group under the app
+    app.blueprint(group)
+
+Exceptions
+~~~~~~~~~~
+
+Exceptions can be applied exclusively to blueprints globally.
+
+.. code-block:: python
+
+    @bp.exception(NotFound)
+    def ignore_404s(request, exception):
+        return text("Yep, I totally found the page: {}".format(request.url))
+
+Static files
+~~~~~~~~~~~~
+
+Static files can be served globally, under the blueprint prefix.
+
+.. code-block:: python
+
+    # suppose bp.name == 'bp'
+
+    bp.static('/web/path', '/folder/to/serve')
+    # also you can pass name parameter to it for url_for
+    bp.static('/web/path', '/folder/to/server', name='uploads')
+    app.url_for('static', name='bp.uploads', filename='file.txt') == '/bp/web/path/file.txt'
+
+Start and stop
+--------------
+
+Blueprints can run functions during the start and stop process of the server.
+If running in multiprocessor mode (more than 1 worker), these are triggered
+after the workers fork.
+

+    bp = Blueprint('my_blueprint')
+
+    @bp.listener('before_server_start')
+    async def setup_connection(app, loop):
+        global database
+        database = mysql.connect(host='127.0.0.1'...)

-# Class-Based Views
-
-Class-based views are simply classes which implement response behaviour to
-requests. They provide a way to compartmentalise handling of different HTTP
-request types at the same endpoint. Rather than defining and decorating three
-different handler functions, one for each of an endpoint's supported request
-type, the endpoint can be assigned a class-based view.
-
-## Defining views
-
-A class-based view should subclass `HTTPMethodView`. You can then implement
-class methods for every HTTP request type you want to support. If a request is
-received that has no defined method, a `405: Method not allowed` response will
-be generated.
-
-To register a class-based view on an endpoint, the `app.add_route` method is
-used. The first argument should be the defined class with the method `as_view`
-invoked, and the second should be the URL endpoint.
-
-The available methods are `get`, `post`, `put`, `patch`, and `delete`. A class
-using all these methods would look like the following.
-
-```python
-from sanic import Sanic
-from sanic.views import HTTPMethodView
-from sanic.response import text
-
-app = Sanic('some_name')
-
-class SimpleView(HTTPMethodView):
-
-  def get(self, request):
-      return text('I am get method')
-
-  def post(self, request):
-      return text('I am post method')
-
-  def put(self, request):
-      return text('I am put method')
-
-  def patch(self, request):
-      return text('I am patch method')
-
-  def delete(self, request):
-      return text('I am delete method')
-
-app.add_route(SimpleView.as_view(), '/')
-
-```
-
-You can also use `async` syntax.
-
-```python
-from sanic import Sanic
-from sanic.views import HTTPMethodView
-from sanic.response import text
-
-app = Sanic('some_name')
-
-class SimpleAsyncView(HTTPMethodView):
-
-  async def get(self, request):
-      return text('I am async get method')
-
-app.add_route(SimpleAsyncView.as_view(), '/')
-
-```
-
-## URL parameters
-
-If you need any URL parameters, as discussed in the routing guide, include them
-in the method definition.
-
-```python
-class NameView(HTTPMethodView):
-
-  def get(self, request, name):
-    return text('Hello {}'.format(name))
-
-app.add_route(NameView.as_view(), '/<name>')
-```
-
-## Decorators
-
-If you want to add any decorators to the class, you can set the `decorators`
-class variable. These will be applied to the class when `as_view` is called.
-
-```python
-class ViewWithDecorator(HTTPMethodView):
-  decorators = [some_decorator_here]
-
-  def get(self, request, name):
-    return text('Hello I have a decorator')
-
-  def post(self, request, name):
-    return text("Hello I also have a decorator")
-
-app.add_route(ViewWithDecorator.as_view(), '/url')
-```
-
-But if you just want to decorate some functions and not all functions, you can do as follows:
-
-```python
-class ViewWithSomeDecorator(HTTPMethodView):
-
-    @staticmethod
-    @some_decorator_here
-    def get(request, name):
-        return text("Hello I have a decorator")
-
-    def post(self, request, name):
-        return text("Hello I don't have any decorators")
-```
-
-## URL Building
-
-If you wish to build a URL for an HTTPMethodView, remember that the class name will be the endpoint
-that you will pass into `url_for`. For example:
-
-```python
-@app.route('/')
-def index(request):
-    url = app.url_for('SpecialClassView')
-    return redirect(url)
-
-
-class SpecialClassView(HTTPMethodView):
-    def get(self, request):
-        return text('Hello from the Special Class View!')
-
-
-app.add_route(SpecialClassView.as_view(), '/special_class_view')
-```
-
-
-## Using CompositionView
-
-As an alternative to the `HTTPMethodView`, you can use `CompositionView` to
-move handler functions outside of the view class.
-
-Handler functions for each supported HTTP method are defined elsewhere in the
-source, and then added to the view using the `CompositionView.add` method. The
-first parameter is a list of HTTP methods to handle (e.g. `['GET', 'POST']`),
-and the second is the handler function. The following example shows
-`CompositionView` usage with both an external handler function and an inline
-lambda:
-
-```python
-from sanic import Sanic
-from sanic.views import CompositionView
-from sanic.response import text
-
-app = Sanic(__name__)
-
-def get_handler(request):
-    return text('I am a get method')
-
-view = CompositionView()
-view.add(['GET'], get_handler)
-view.add(['POST', 'PUT'], lambda request: text('I am a post/put method'))
-
-# Use the new view to handle requests to the base URL
-app.add_route(view, '/')
-```
-
-Note: currently you cannot build a URL for a CompositionView using `url_for`.

-# Configuration
-
-Any reasonably complex application will need configuration that is not baked into the actual code. Settings might be different for different environments or installations.
-
-## Basics
-
-Sanic holds the configuration in the `config` attribute of the application object. The configuration object is merely an object that can be modified either using dot-notation or like a dictionary:
-
-```
-app = Sanic('myapp')
-app.config.DB_NAME = 'appdb'
-app.config.DB_USER = 'appuser'
-```
-
-Since the config object actually is a dictionary, you can use its `update` method in order to set several values at once:
-
-```
-db_settings = {
-    'DB_HOST': 'localhost',
-    'DB_NAME': 'appdb',
-    'DB_USER': 'appuser'
-}
-app.config.update(db_settings)
-```
-
-In general the convention is to only have UPPERCASE configuration parameters. The methods described below for loading configuration only look for such uppercase parameters.
-
-## Loading Configuration
-
-There are several ways how to load configuration.
-
-### From Environment Variables
-
-Any variables defined with the `SANIC_` prefix will be applied to the sanic config. For example, setting `SANIC_REQUEST_TIMEOUT` will be loaded by the application automatically and fed into the `REQUEST_TIMEOUT` config variable. You can pass a different prefix to Sanic:
-
-```python
-app = Sanic(load_env='MYAPP_')
-```
-
-Then the above variable would be `MYAPP_REQUEST_TIMEOUT`. If you want to disable loading from environment variables you can set it to `False` instead:
-
-```python
-app = Sanic(load_env=False)
-```
-
-### From an Object
-
-If there are a lot of configuration values and they have sensible defaults it might be helpful to put them into a module:
-
-```
-import myapp.default_settings
-
-app = Sanic('myapp')
-app.config.from_object(myapp.default_settings)
-```
-
-You could use a class or any other object as well.
-
-### From a File
-
-Usually you will want to load configuration from a file that is not part of the distributed application. You can load configuration from a file using `from_pyfile(/path/to/config_file)`. However, that requires the program to know the path to the config file. So instead you can specify the location of the config file in an environment variable and tell Sanic to use that to find the config file:
-
-```
-app = Sanic('myapp')
-app.config.from_envvar('MYAPP_SETTINGS')
-```
-
-Then you can run your application with the `MYAPP_SETTINGS` environment variable set:
-
-```
-$ MYAPP_SETTINGS=/path/to/config_file python3 myapp.py
-INFO: Goin' Fast @ http://0.0.0.0:8000
-```
-
-The config files are regular Python files which are executed in order to load them. This allows you to use arbitrary logic for constructing the right configuration. Only uppercase variables are added to the configuration. Most commonly the configuration consists of simple key value pairs:
-
-```
-# config_file
-DB_HOST = 'localhost'
-DB_NAME = 'appdb'
-DB_USER = 'appuser'
-```
-
-## Builtin Configuration Values
-
-Out of the box there are just a few predefined values which can be overwritten when creating the application.
-
-    | Variable                  | Default   | Description                                            |
-    | ------------------------- | --------- | ------------------------------------------------------ |
-    | REQUEST_MAX_SIZE          | 100000000 | How big a request may be (bytes)                       |
-    | REQUEST_TIMEOUT           | 60        | How long a request can take to arrive (sec)            |
-    | RESPONSE_TIMEOUT          | 60        | How long a response can take to process (sec)          |
-    | KEEP_ALIVE                | True      | Disables keep-alive when False                         |
-    | KEEP_ALIVE_TIMEOUT        | 5         | How long to hold a TCP connection open (sec)           |
-    | GRACEFUL_SHUTDOWN_TIMEOUT | 15.0      | How long take to force close non-idle connection (sec) |
-    | ACCESS_LOG                | True      | Disable or enable access log                           |
-
-### The different Timeout variables:
-
-A request timeout measures the duration of time between the instant when a new open TCP connection is passed to the Sanic backend server, and the instant when the whole HTTP request is received. If the time taken exceeds the `REQUEST_TIMEOUT` value (in seconds), this is considered a Client Error so Sanic generates a HTTP 408 response and sends that to the client. Adjust this value higher if your clients routinely pass very large request payloads or upload requests very slowly.
-
-A response timeout measures the duration of time between the instant the Sanic server passes the HTTP request to the Sanic App, and the instant a HTTP response is sent to the client. If the time taken exceeds the `RESPONSE_TIMEOUT` value (in seconds), this is considered a Server Error so Sanic generates a HTTP 503 response and sets that to the client. Adjust this value higher if your application is likely to have long-running process that delay the generation of a response.
-
-### What is Keep Alive? And what does the Keep Alive Timeout value do?
-
-Keep-Alive is a HTTP feature indroduced in HTTP 1.1. When sending a HTTP request, the client (usually a web browser application) can set a Keep-Alive header to indicate for the http server (Sanic) to not close the TCP connection after it has send the response. This allows the client to reuse the existing TCP connection to send subsequent HTTP requests, and ensures more efficient network traffic for both the client and the server.
-
-The `KEEP_ALIVE` config variable is set to `True` in Sanic by default. If you don't need this feature in your application, set it to `False` to cause all client connections to close immediately after a response is sent, regardless of the Keep-Alive header on the request.
-
-The amount of time the server holds the TCP connection open is decided by the server itself. In Sanic, that value is configured using the `KEEP_ALIVE_TIMEOUT` value. By default, it is set to 5 seconds, this is the same default setting as the Apache HTTP server and is a good balance between allowing enough time for the client to send a new request, and not holding open too many connections at once. Do not exceed 75 seconds unless you know your clients are using a browser which supports TCP connections held open for that long.
-
-For reference:
-```
-Apache httpd server default keepalive timeout = 5 seconds
-Nginx server default keepalive timeout = 75 seconds
-Nginx performance tuning guidelines uses keepalive = 15 seconds
-IE (5-9) client hard keepalive limit = 60 seconds
-Firefox client hard keepalive limit = 115 seconds
-Opera 11 client hard keepalive limit = 120 seconds
-Chrome 13+ client keepalive limit > 300+ seconds

+
+The different Timeout variables:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`REQUEST_TIMEOUT`
+#################
+
+A request timeout measures the duration of time between the instant when a new open TCP connection is passed to the
+Sanic backend server, and the instant when the whole HTTP request is received. If the time taken exceeds the
+`REQUEST_TIMEOUT` value (in seconds), this is considered a Client Error so Sanic generates an `HTTP 408` response
+and sends that to the client. Set this parameter's value higher if your clients routinely pass very large request payloads
+or upload requests very slowly.
+
+`RESPONSE_TIMEOUT`
+##################
+
+A response timeout measures the duration of time between the instant the Sanic server passes the HTTP request to the
+Sanic App, and the instant a HTTP response is sent to the client. If the time taken exceeds the `RESPONSE_TIMEOUT`
+value (in seconds), this is considered a Server Error so Sanic generates an `HTTP 503` response and sends that to the
+client. Set this parameter's value higher if your application is likely to have long-running process that delay the
+generation of a response.
+
+`KEEP_ALIVE_TIMEOUT`
+####################
+
+What is Keep Alive? And what does the Keep Alive Timeout value do?
+******************************************************************
+
+`Keep-Alive` is a HTTP feature introduced in `HTTP 1.1`. When sending a HTTP request, the client (usually a web browser application)
+can set a `Keep-Alive` header to indicate the http server (Sanic) to not close the TCP connection after it has send the response.
+This allows the client to reuse the existing TCP connection to send subsequent HTTP requests, and ensures more efficient
+network traffic for both the client and the server.
+
+The `KEEP_ALIVE` config variable is set to `True` in Sanic by default. If you don't need this feature in your application,
+set it to `False` to cause all client connections to close immediately after a response is sent, regardless of
+the `Keep-Alive` header on the request.
+
+The amount of time the server holds the TCP connection open is decided by the server itself.
+In Sanic, that value is configured using the `KEEP_ALIVE_TIMEOUT` value. By default, it is set to 5 seconds.
+This is the same default setting as the Apache HTTP server and is a good balance between allowing enough time for
+the client to send a new request, and not holding open too many connections at once. Do not exceed 75 seconds unless
+you know your clients are using a browser which supports TCP connections held open for that long.
+
+For reference:
+
+* Apache httpd server default keepalive timeout = 5 seconds
+* Nginx server default keepalive timeout = 75 seconds
+* Nginx performance tuning guidelines uses keepalive = 15 seconds
+* IE (5-9) client hard keepalive limit = 60 seconds
+* Firefox client hard keepalive limit = 115 seconds
+* Opera 11 client hard keepalive limit = 120 seconds
+* Chrome 13+ client keepalive limit > 300+ seconds
+
+
+Proxy configuration
+~~~~~~~~~~~~~~~~~~~
+
+When you use a reverse proxy server (e.g. nginx), the value of `request.ip` will contain ip of a proxy,
+typically `127.0.0.1`. Sanic may be configured to use proxy headers for determining the true client IP,
+available as `request.remote_addr`. The full external URL is also constructed from header fields if available.
+
+Without proper precautions, a malicious client may use proxy headers to spoof its own IP. To avoid such issues, Sanic does not use any proxy headers unless explicitly enabled.
+
+Services behind reverse proxies must configure `FORWARDED_SECRET`, `REAL_IP_HEADER` and/or `PROXIES_COUNT`.
+
+Forwarded header
+################
+
+.. Forwarded: for="1.2.3.4"; proto="https"; host="yoursite.com"; secret="Pr0xy", for="10.0.0.1"; proto="http"; host="proxy.internal"; by="_1234proxy"
+
+* Set `FORWARDED_SECRET` to an identifier used by the proxy of interest.
+
+The secret is used to securely identify a specific proxy server. Given the above header, secret `Pr0xy` would use the
+information on the first line and secret `_1234proxy` would use the second line. The secret must exactly match the value
+of `secret` or `by`. A secret in `by` must begin with an underscore and use only characters specified in
+`RFC 7239 section 6.3 <https://tools.ietf.org/html/rfc7239#section-6.3>`_, while `secret` has no such restrictions.
+
+Sanic ignores any elements without the secret key, and will not even parse the header if no secret is set.
+
+All other proxy headers are ignored once a trusted forwarded element is found, as it already carries complete information about the client.
+
+Traditional proxy headers
+#########################
+
+..  X-Real-IP: 1.2.3.4
+    X-Forwarded-For: 1.2.3.4, 10.0.0.1
+    X-Forwarded-Proto: https
+    X-Forwarded-Host: yoursite.com
+
+
+* Set `REAL_IP_HEADER` to `x-real-ip`, `true-client-ip`, `cf-connecting-ip` or other name of such header.
+* Set `PROXIES_COUNT` to the number of entries expected in `x-forwarded-for` (name configurable via `FORWARDED_FOR_HEADER`).
+
+If client IP is found by one of these methods, Sanic uses the following headers for URL parts:
+
+* `x-forwarded-proto`, `x-forwarded-host`, `x-forwarded-port`, `x-forwarded-path` and if necessary, `x-scheme`.
+
+Proxy config if using ...
+#########################
+
+* a proxy that supports `forwarded`: set `FORWARDED_SECRET` to the value that the proxy inserts in the header
+    * Apache Traffic Server: `CONFIG proxy.config.http.insert_forwarded STRING for|proto|host|by=_secret`
+    * NGHTTPX: `nghttpx --add-forwarded=for,proto,host,by --forwarded-for=ip --forwarded-by=_secret`
+    * NGINX: after `the official instructions <https://www.nginx.com/resources/wiki/start/topics/examples/forwarded/>`_, add anywhere in your config:
+
+..        proxy_set_header Forwarded "$proxy_add_forwarded;by=\"_$server_name\";proto=$scheme;host=\"$http_host\";path=\"$request_uri\";secret=_secret";
+
+* a custom header with client IP: set `REAL_IP_HEADER` to the name of that header
+* `x-forwarded-for`: set `PROXIES_COUNT` to `1` for a single proxy, or a greater number to allow Sanic to select the correct IP
+* no proxies: no configuration required!
+
+Changes in Sanic 19.9
+#####################
+
+Earlier Sanic versions had unsafe default settings. From 19.9 onwards proxy settings must be set manually, and support for negative PROXIES_COUNT has been removed.

-# Custom Protocols
-
-*Note: this is advanced usage, and most readers will not need such functionality.*
-
-You can change the behavior of Sanic's protocol by specifying a custom
-protocol, which should be a subclass
-of
-[asyncio.protocol](https://docs.python.org/3/library/asyncio-protocol.html#protocol-classes).
-This protocol can then be passed as the keyword argument `protocol` to the `sanic.run` method.
-
-The constructor of the custom protocol class receives the following keyword
-arguments from Sanic.
-
-- `loop`: an `asyncio`-compatible event loop.
-- `connections`: a `set` to store protocol objects. When Sanic receives
-  `SIGINT` or `SIGTERM`, it executes `protocol.close_if_idle` for all protocol
-  objects stored in this set.
-- `signal`: a `sanic.server.Signal` object with the `stopped` attribute. When
-  Sanic receives `SIGINT` or `SIGTERM`, `signal.stopped` is assigned `True`.
-- `request_handler`: a coroutine that takes a `sanic.request.Request` object
-  and a `response` callback as arguments.
-- `error_handler`: a `sanic.exceptions.Handler` which is called when exceptions
-  are raised.
-- `request_timeout`: the number of seconds before a request times out.
-- `request_max_size`: an integer specifying the maximum size of a request, in bytes.
-

-
-An error occurs in the default protocol if a handler function does not return
-an `HTTPResponse` object.

-# Deploying
-
-Deploying Sanic is made simple by the inbuilt webserver. After defining an
-instance of `sanic.Sanic`, we can call the `run` method with the following
-keyword arguments:
-
-- `host` *(default `"127.0.0.1"`)*: Address to host the server on.
-- `port` *(default `8000`)*: Port to host the server on.
-- `debug` *(default `False`)*: Enables debug output (slows server).
-- `ssl` *(default `None`)*: `SSLContext` for SSL encryption of worker(s).
-- `sock` *(default `None`)*: Socket for the server to accept connections from.
-- `workers` *(default `1`)*: Number of worker processes to spawn.
-- `loop` *(default `None`)*: An `asyncio`-compatible event loop. If none is
-                             specified, Sanic creates its own event loop.
-- `protocol` *(default `HttpProtocol`)*: Subclass
-  of
-  [asyncio.protocol](https://docs.python.org/3/library/asyncio-protocol.html#protocol-classes).
-
-## Workers
-
-By default, Sanic listens in the main process using only one CPU core. To crank
-up the juice, just specify the number of workers in the `run` arguments.
-
-```python
-app.run(host='0.0.0.0', port=1337, workers=4)
-```
-
-Sanic will automatically spin up multiple processes and route traffic between
-them. We recommend as many workers as you have available cores.
-
-## Running via command
-
-If you like using command line arguments, you can launch a Sanic server by
-executing the module. For example, if you initialized Sanic as `app` in a file
-named `server.py`, you could run the server like so:
-
-`python -m sanic server.app --host=0.0.0.0 --port=1337 --workers=4`
-
-With this way of running sanic, it is not necessary to invoke `app.run` in your
-Python file. If you do, make sure you wrap it so that it only executes when
-directly run by the interpreter.
-
-```python
-if __name__ == '__main__':
-    app.run(host='0.0.0.0', port=1337, workers=4)
-```
-
-## Running via Gunicorn
-
-[Gunicorn](http://gunicorn.org/) ‘Green Unicorn’ is a WSGI HTTP Server for UNIX.
-It’s a pre-fork worker model ported from Ruby’s Unicorn project.
-
-In order to run Sanic application with Gunicorn, you need to use the special `sanic.worker.GunicornWorker`
-for Gunicorn `worker-class` argument:
-
-```
-gunicorn myapp:app --bind 0.0.0.0:1337 --worker-class sanic.worker.GunicornWorker
-```
-
-If your application suffers from memory leaks, you can configure Gunicorn to gracefully restart a worker
-after it has processed a given number of requests. This can be a convenient way to help limit the effects
-of the memory leak.
-
-See the [Gunicorn Docs](http://docs.gunicorn.org/en/latest/settings.html#max-requests) for more information.
-
-## Asynchronous support
-This is suitable if you *need* to share the sanic process with other applications, in particular the `loop`.
-However be advised that this method does not support using multiple processes, and is not the preferred way
-to run the app in general.
-
-Here is an incomplete example (please see `run_async.py` in examples for something more practical):
-
-```python
-server = app.create_server(host="0.0.0.0", port=8000)
-loop = asyncio.get_event_loop()
-task = asyncio.ensure_future(server)
-loop.run_forever()
-```

+named `server.py`, you could run the server like so:
+
+.. python -m sanic server.app --host=0.0.0.0 --port=1337 --workers=4
+
+With this way of running sanic, it is not necessary to invoke `app.run` in your
+Python file. If you do, make sure you wrap it so that it only executes when
+directly run by the interpreter.
+
+.. code-block:: python
+
+    if __name__ == '__main__':
+        app.run(host='0.0.0.0', port=1337, workers=4)
+
+Running via ASGI
+----------------
+
+Sanic is also ASGI-compliant. This means you can use your preferred ASGI webserver
+to run Sanic. The three main implementations of ASGI are
+`Daphne <http://github.com/django/daphne>`_, `Uvicorn <https://www.uvicorn.org/>`_,
+and `Hypercorn <https://pgjones.gitlab.io/hypercorn/index.html>`_.
+
+Follow their documentation for the proper way to run them, but it should look
+something like:
+
+::
+
+    daphne myapp:app
+    uvicorn myapp:app
+    hypercorn myapp:app
+
+A couple things to note when using ASGI:
+
+1. When using the Sanic webserver, websockets will run using the `websockets <https://websockets.readthedocs.io/>`_ package.
+In ASGI mode, there is no need for this package since websockets are managed in the ASGI server.
+2. The ASGI `lifespan protocol <https://asgi.readthedocs.io/en/latest/specs/lifespan.html>`, supports
+only two server events: startup and shutdown. Sanic has four: before startup, after startup,
+before shutdown, and after shutdown. Therefore, in ASGI mode, the startup and shutdown events will
+run consecutively and not actually around the server process beginning and ending (since that
+is now controlled by the ASGI server). Therefore, it is best to use `after_server_start` and
+`before_server_stop`.
+3. ASGI mode is still in "beta" as of Sanic v19.6.
+
+Running via Gunicorn
+--------------------
+
+`Gunicorn <http://gunicorn.org/>`_ ‘Green Unicorn’ is a WSGI HTTP Server for UNIX.
+It’s a pre-fork worker model ported from Ruby’s Unicorn project.
+
+In order to run Sanic application with Gunicorn, you need to use the special `sanic.worker.GunicornWorker`
+for Gunicorn `worker-class` argument:
+
+::
+
+    gunicorn myapp:app --bind 0.0.0.0:1337 --worker-class sanic.worker.GunicornWorker
+
+
+If your application suffers from memory leaks, you can configure Gunicorn to gracefully restart a worker
+after it has processed a given number of requests. This can be a convenient way to help limit the effects
+of the memory leak.
+
+See the `Gunicorn Docs <http://docs.gunicorn.org/en/latest/settings.html#max-requests>`_ for more information.
+
+Other deployment considerations
+-------------------------------
+
+Running behind a reverse proxy
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sanic can be used with a reverse proxy (e.g. nginx). There's a simple example of nginx configuration:
+
+
+::
+
+    server {
+      listen 80;
+      server_name example.org;
+      location / {
+        proxy_pass http://127.0.0.1:8000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+      }
+    }
+
+
+If you want to get real client ip, you should configure `X-Real-IP` and `X-Forwarded-For` HTTP headers and set `app.config.PROXIES_COUNT` to `1`; see the configuration page for more information.
+
+Disable debug logging for performance
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To improve the performance add `debug=False` and `access_log=False` in the `run` arguments.
+
+.. code-block:: python
+
+    app.run(host='0.0.0.0', port=1337, workers=4, debug=False, access_log=False)
+
+Running via Gunicorn you can set Environment variable `SANIC_ACCESS_LOG="False"`
+
+::
+
+    env SANIC_ACCESS_LOG="False" gunicorn myapp:app --bind 0.0.0.0:1337 --worker-class sanic.worker.GunicornWorker --log-level warning
+
+Or you can rewrite app config directly
+
+.. code-block:: python
+
+    app.config.ACCESS_LOG = False
+
+Asynchronous support and sharing the loop
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is suitable if you *need* to share the Sanic process with other applications, in particular the `loop`.
+However, be advised that this method does not support using multiple processes, and is not the preferred way
+to run the app in general.
+
+Here is an incomplete example (please see `run_async.py` in examples for something more practical):
+
+.. code-block:: python
+
+    server = app.create_server(host="0.0.0.0", port=8000, return_asyncio_server=True)
+    loop = asyncio.get_event_loop()
+    task = asyncio.ensure_future(server)
+    loop.run_forever()
+
+Caveat: using this method, calling `app.create_server()` will trigger "before_server_start" server events, but not
+"after_server_start", "before_server_stop", or "after_server_stop" server events.
+
+For more advanced use-cases, you can trigger these events using the AsyncioServer object, returned by awaiting
+the server task.
+
+Here is an incomplete example (please see `run_async_advanced.py` in examples for something more complete):
+
+.. code-block:: python
+
+    serv_coro = app.create_server(host="0.0.0.0", port=8000, return_asyncio_server=True)
+    loop = asyncio.get_event_loop()
+    serv_task = asyncio.ensure_future(serv_coro, loop=loop)
+    server = loop.run_until_complete(serv_task)
+    server.after_start()
+    try:
+        loop.run_forever()
+    except KeyboardInterrupt as e:
+        loop.stop()
+    finally:
+        server.before_stop()
+
+        # Wait for server to close
+        close_task = server.close()
+        loop.run_until_complete(close_task)
+
+        # Complete all tasks on the loop
+        for connection in server.connections:
+            connection.close_if_idle()
+        server.after_stop()

+Examples
+========
+
+This section of the documentation is a simple collection of example code that can help you get a quick start
+on your application development. Most of these examples are categorized and provide you with a link to the
+working code example in the `Sanic Repository <https://github.com/huge-success/sanic/tree/master/examples>`_
+
+
+Basic Examples
+--------------
+
+This section of the examples are a collection of code that provide a simple use case example of the sanic application.
+
+Simple Apps
+~~~~~~~~~~~~
+
+A simple sanic application with a single ``async`` method with ``text`` and ``json`` type response.
+
+
+.. literalinclude:: ../../examples/teapot.py
+
+.. literalinclude:: ../../examples/simple_server.py
+
+
+Simple App with ``Sanic Views``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Showcasing the simple mechanism of using :class:`sanic.viewes.HTTPMethodView` as well as a way to extend the same
+into providing a custom ``async`` behavior for ``view``.
+
+.. literalinclude:: ../../examples/simple_async_view.py
+
+
+URL Redirect
+~~~~~~~~~~~~
+
+.. literalinclude:: ../../examples/redirect_example.py
+
+
+Named URL redirection
+~~~~~~~~~~~~~~~~~~~~~
+
+``Sanic`` provides an easy to use way of redirecting the requests via a helper method called ``url_for`` that takes a
+unique url name as argument and returns you the actual route assigned for it. This will help in simplifying the
+efforts required in redirecting the user between different section of the application.
+
+.. literalinclude:: ../../examples/url_for_example.py
+
+Blueprints
+~~~~~~~~~~
+``Sanic`` provides an amazing feature to group your APIs and routes under a logical collection that can easily be
+imported and plugged into any of your sanic application and it's called ``blueprints``
+
+.. literalinclude:: ../../examples/blueprints.py
+
+Logging Enhancements
+~~~~~~~~~~~~~~~~~~~~
+
+Even though ``Sanic`` comes with a battery of Logging support it allows the end users to customize the way logging
+is handled in the application runtime.
+
+.. literalinclude:: ../../examples/override_logging.py
+
+The following sample provides an example code that demonstrates the usage of :func:`sanic.app.Sanic.middleware` in order
+to provide a mechanism to assign a unique request ID for each of the incoming requests and log them via
+`aiotask-context <https://github.com/Skyscanner/aiotask-context>`_.
+
+
+.. literalinclude:: ../../examples/log_request_id.py
+
+Sanic Streaming Support
+~~~~~~~~~~~~~~~~~~~~~~~
+
+``Sanic`` framework comes with in-built support for streaming large files and the following code explains the process
+to setup a ``Sanic`` application with streaming support.
+
+.. literalinclude:: ../../examples/request_stream/server.py
+
+Sample Client app to show the usage of streaming application by a client code.
+
+.. literalinclude:: ../../examples/request_stream/client.py
+
+Sanic Concurrency Support
+~~~~~~~~~~~~~~~~~~~~~~~~~
+``Sanic`` supports the ability to start an app with multiple worker support. However, it's important to be able to limit
+the concurrency per process/loop in order to ensure an efficient execution. The following section of the code provides a
+brief example of how to limit the concurrency with the help of :class:`asyncio.Semaphore`
+
+.. literalinclude:: ../../examples/limit_concurrency.py
+
+
+Sanic Deployment via Docker
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Deploying a ``sanic`` app via ``docker`` and ``docker-compose`` is an easy task to achieve and the following example
+provides a deployment of the sample ``simple_server.py``
+
+.. literalinclude:: ../../examples/Dockerfile
+
+.. literalinclude:: ../../examples/docker-compose.yml
+
+
+Monitoring and Error Handling
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+``Sanic`` provides an extendable bare minimum implementation of a global exception handler via
+:class:`sanic.handlers.ErrorHandler`. This example shows how to extend it to enable some custom behaviors.
+
+.. literalinclude:: ../../examples/exception_monitoring.py
+
+Monitoring using external Service Providers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* `LogDNA <https://logdna.com/>`_
+

+
+The following sample code shows a simple decorator based authentication and authorization mechanism that can be setup
+to secure your ``sanic`` api endpoints.
+
+.. literalinclude:: ../../examples/authorized_sanic.py
+
+Sanic Websocket
+~~~~~~~~~~~~~~~
+
+``Sanic`` provides an ability to easily add a route and map it to a ``websocket`` handlers.
+
+.. literalinclude:: ../../examples/websocket.html
+.. literalinclude:: ../../examples/websocket.py
+
+vhost Suppport
+~~~~~~~~~~~~~~

+Unit Testing With Parallel Test Run Support
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following example shows you how to get up and running with unit testing ``sanic`` application with parallel test
+execution support provided by the ``pytest-xdist`` plugin.
+
+.. literalinclude:: ../../examples/pytest_xdist.py
+
+
+Amending Request Object
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``request`` object in ``Sanic`` is a kind of ``dict`` object, this means that ``request`` object can be manipulated as a regular ``dict`` object.
+
+.. literalinclude:: ../../examples/amending_request_object.py

-# Exceptions
-
-Exceptions can be thrown from within request handlers and will automatically be
-handled by Sanic. Exceptions take a message as their first argument, and can
-also take a status code to be passed back in the HTTP response.
-
-## Throwing an exception
-
-To throw an exception, simply `raise` the relevant exception from the
-`sanic.exceptions` module.
-
-```python
-from sanic.exceptions import ServerError
-
-@app.route('/killme')
-async def i_am_ready_to_die(request):
-	raise ServerError("Something bad happened", status_code=500)
-```
-
-You can also use the `abort` function with the appropriate status code:
-
-```python
-from sanic.exceptions import abort
-from sanic.response import text
-
-@app.route('/youshallnotpass')
-async def no_no(request):
-        abort(401)
-        # this won't happen
-        text("OK")
-```
-
-## Handling exceptions
-
-To override Sanic's default handling of an exception, the `@app.exception`
-decorator is used. The decorator expects a list of exceptions to handle as
-arguments. You can pass `SanicException` to catch them all! The decorated
-exception handler function must take a `Request` and `Exception` object as
-arguments.
-
-```python
-from sanic.response import text
-from sanic.exceptions import NotFound
-
-@app.exception(NotFound)
-async def ignore_404s(request, exception):
-	return text("Yep, I totally found the page: {}".format(request.url))
-```
-
-You can also add an exception handler as such:
-
-```python
-from sanic import Sanic
-
-async def server_error_handler(request, exception):
-	return text("Oops, server error", status=500)
-
-app = Sanic()
-app.error_handler.add(Exception, server_error_handler)
-```
-
-In some cases, you might want want to add some more error handling
-functionality to what is provided by default. In that case, you 
-can subclass Sanic's default error handler as such:
-
-```python
-from sanic import Sanic
-from sanic.handlers import ErrorHandler
-
-class CustomErrorHandler(ErrorHandler):
-	def default(self, request, exception):
-		''' handles errors that have no error handlers assigned '''
-		# You custom error handling logic...
-		return super().default(request, exception)
-		
-app = Sanic()
-app.error_handler = CustomErrorHandler()
-```
-
-## Useful exceptions
-
-Some of the most useful exceptions are presented below:
-
-- `NotFound`: called when a suitable route for the request isn't found.
-- `ServerError`: called when something goes wrong inside the server. This
-  usually occurs if there is an exception raised in user code.

-Sanic is a Flask-like Python 3.5+ web server that's written to go fast.  It's based on the work done by the amazing folks at magicstack, and was inspired by `this article <https://magic.io/blog/uvloop-blazing-fast-python-networking/>`_.
+Sanic is a Python 3.6+ web server and web framework that's written to go fast. It allows the usage of the async/await syntax added in Python 3.5, which makes your code non-blocking and speedy.
 
-On top of being Flask-like, Sanic supports async request handlers.  This means you can use the new shiny async/await syntax from Python 3.5, making your code non-blocking and speedy.
+The goal of the project is to provide a simple way to get up and running a highly performant HTTP server that is easy to build, to expand, and ultimately to scale.
 
 Sanic is developed `on GitHub <https://github.com/channelcat/sanic/>`_. Contributions are welcome!

-# Logging
-
-
-Sanic allows you to do different types of logging (access log, error log) on the requests based on the [python3 logging API](https://docs.python.org/3/howto/logging.html). You should have some basic knowledge on python3 logging if you want to create a new configuration.
-
-### Quick Start
-
-A simple example using default settings would be like this:
-
-```python
-from sanic import Sanic
-from sanic.log import logger
-from sanic.response import text
-
-app = Sanic('test')
-
-@app.route('/')
-async def test(request):
-    logger.info('Here is your log')
-    return text('Hello World!')
-
-if __name__ == "__main__":
-  app.run(debug=True, access_log=True)
-```
-
-After the server is running, you can see some messages looks like:
-```
-[2018-11-06 21:16:53 +0800] [24622] [INFO] Goin' Fast @ http://127.0.0.1:8000
-[2018-11-06 21:16:53 +0800] [24667] [INFO] Starting worker [24667]
-```
-
-You can send a request to server and it will print the log messages:
-```
-[2018-11-06 21:18:53 +0800] [25685] [INFO] Here is your log
-[2018-11-06 21:18:53 +0800] - (sanic.access)[INFO][127.0.0.1:57038]: GET http://localhost:8000/  200 12
-```
-
-To use your own logging config, simply use `logging.config.dictConfig`, or
-pass `log_config` when you initialize `Sanic` app:
-
-```python
-app = Sanic('test', log_config=LOGGING_CONFIG)
-```
-
-And to close logging, simply assign access_log=False:
-
-```python
-if __name__ == "__main__":
-  app.run(access_log=False)
-```
-
-This would skip calling logging functions when handling requests.
-And you could even do further in production to gain extra speed:
-
-```python
-if __name__ == "__main__":
-  # disable debug messages
-  app.run(debug=False, access_log=False)
-```
-
-### Configuration
-
-By default, log_config parameter is set to use sanic.log.LOGGING_CONFIG_DEFAULTS dictionary for configuration.
-
-There are three `loggers` used in sanic, and **must be defined if you want to create your own logging configuration**:
-
-- sanic.root:<br>
-  Used to log internal messages.
-
-- sanic.error:<br>
-  Used to log error logs.
-
-- sanic.access:<br>
-  Used to log access logs.
-
-#### Log format:
-
-In addition to default parameters provided by python (asctime, levelname, message),
-Sanic provides additional parameters for access logger with:
-
-- host (str)<br>
-  request.ip
-
-
-- request (str)<br>
-  request.method + " " + request.url
-
-
-- status (int)<br>
-  response.status
-
-
-- byte (int)<br>
-  len(response.body)
-
-
-The default access log format is 
-```python
-%(asctime)s - (%(name)s)[%(levelname)s][%(host)s]: %(request)s %(message)s %(status)d %(byte)d
-```

-# Middleware And Listeners
-
-Middleware are functions which are executed before or after requests to the
-server. They can be used to modify the *request to* or *response from*
-user-defined handler functions.
-
-Additionally, Sanic provides listeners which allow you to run code at various points of your application's lifecycle.
-
-## Middleware
-
-There are two types of middleware: request and response. Both are declared
-using the `@app.middleware` decorator, with the decorator's parameter being a
-string representing its type: `'request'` or `'response'`.
-
-* Request middleware receives only the `request` as argument.
-* Response middleware receives both the `request` and `response`.
-
-The simplest middleware doesn't modify the request or response at all:
-
-```
-@app.middleware('request')
-async def print_on_request(request):
-	print("I print when a request is received by the server")
-
-@app.middleware('response')
-async def print_on_response(request, response):
-	print("I print when a response is returned by the server")
-```
-
-## Modifying the request or response
-
-Middleware can modify the request or response parameter it is given, *as long
-as it does not return it*. The following example shows a practical use-case for
-this.
-
-```
-app = Sanic(__name__)
-
-@app.middleware('response')
-async def custom_banner(request, response):
-	response.headers["Server"] = "Fake-Server"
-
-@app.middleware('response')
-async def prevent_xss(request, response):
-	response.headers["x-xss-protection"] = "1; mode=block"
-
-app.run(host="0.0.0.0", port=8000)
-```
-
-The above code will apply the two middleware in order. First, the middleware
-**custom_banner** will change the HTTP response header *Server* to
-*Fake-Server*, and the second middleware **prevent_xss** will add the HTTP
-header for preventing Cross-Site-Scripting (XSS) attacks. These two functions
-are invoked *after* a user function returns a response.
-
-## Responding early
-
-If middleware returns a `HTTPResponse` object, the request will stop processing
-and the response will be returned. If this occurs to a request before the
-relevant user route handler is reached, the handler will never be called.
-Returning a response will also prevent any further middleware from running.
-
-```
-@app.middleware('request')
-async def halt_request(request):
-	return text('I halted the request')
-
-@app.middleware('response')
-async def halt_response(request, response):
-	return text('I halted the response')
-```
-
-## Listeners
-
-If you want to execute startup/teardown code as your server starts or closes, you can use the following listeners:
-
-- `before_server_start`
-- `after_server_start`
-- `before_server_stop`
-- `after_server_stop`
-
-These listeners are implemented as decorators on functions which accept the app object as well as the asyncio loop.
-
-For example:
-
-```
-@app.listener('before_server_start')
-async def setup_db(app, loop):
-    app.db = await db_setup()
-
-@app.listener('after_server_start')
-async def notify_server_started(app, loop):
-    print('Server successfully started!')
-
-@app.listener('before_server_stop')
-async def notify_server_stopping(app, loop):
-    print('Server shutting down!')
-
-@app.listener('after_server_stop')
-async def close_db(app, loop):
-    await app.db.close()
-```
-
-It's also possible to register a listener using the `register_listener` method.
-This may be useful if you define your listeners in another module besides
-the one you instantiate your app in.
-
-```
-app = Sanic()
-
-async def setup_db(app, loop):
-    app.db = await db_setup()
-
-app.register_listener(setup_db, 'before_server_start')
-
-```
-
-If you want to schedule a background task to run after the loop has started,
-Sanic provides the `add_task` method to easily do so.
-
-```
-async def notify_server_started_after_five_seconds():
-    await asyncio.sleep(5)
-    print('Server successfully started!')
-
-app.add_task(notify_server_started_after_five_seconds())
-```
-
-Sanic will attempt to automatically inject the app, passing it as an argument to the task:
-
-```
-async def notify_server_started_after_five_seconds(app):
-    await asyncio.sleep(5)
-    print(app.name)
-
-app.add_task(notify_server_started_after_five_seconds)
-```
-
-Or you can pass the app explicitly for the same effect:
-
-```
-async def notify_server_started_after_five_seconds(app):
-    await asyncio.sleep(5)
-    print(app.name)
-
-app.add_task(notify_server_started_after_five_seconds(app))

+Additionally, Sanic provides listeners which allow you to run code at various points of your application's lifecycle.
+
+Middleware
+----------
+
+There are two types of middleware: request and response. Both are declared
+using the `@app.middleware` decorator, with the decorator's parameter being a
+string representing its type: `'request'` or `'response'`.
+
+* Request middleware receives only the `request` as argument.

+    @app.middleware('response')
+    async def print_on_response(request, response):
+        print("I print when a response is returned by the server")
+
+Modifying the request or response
+---------------------------------
+
+Middleware can modify the request or response parameter it is given, *as long
+as it does not return it*. The following example shows a practical use-case for
+this.
+
+.. code-block:: python
+
+    app = Sanic(__name__)
+
+
+    @app.middleware('request')
+    async def add_key(request):
+        # Arbitrary data may be stored in request context:
+        request.ctx.foo = 'bar'
+
+
+    @app.middleware('response')
+    async def custom_banner(request, response):
+        response.headers["Server"] = "Fake-Server"
+
+
+    @app.middleware('response')
+    async def prevent_xss(request, response):
+        response.headers["x-xss-protection"] = "1; mode=block"
+
+
+    @app.get("/")
+    async def index(request):
+        return sanic.response.text(request.ctx.foo)
+
+
+    app.run(host="0.0.0.0", port=8000)
+
+The three middlewares are executed in order:
+
+1. The first request middleware **add_key** adds a new key `foo` into request context.
+2. Request is routed to handler **index**, which gets the key from context and returns a text response.
+3. The first response middleware **custom_banner** changes the HTTP response header *Server* to say *Fake-Server*
+4. The second response middleware **prevent_xss** adds the HTTP header for preventing Cross-Site-Scripting (XSS) attacks.
+
+Responding early
+----------------
+
+If middleware returns a `HTTPResponse` object, the request will stop processing
+and the response will be returned. If this occurs to a request before the
+relevant user route handler is reached, the handler will never be called.
+Returning a response will also prevent any further middleware from running.
+
+.. code-block:: python
+
+    @app.middleware('request')
+    async def halt_request(request):
+        return text('I halted the request')
+
+    @app.middleware('response')
+    async def halt_response(request, response):
+        return text('I halted the response')
+
+Custom context
+--------------
+
+Arbitrary data may be stored in `request.ctx`. A typical use case
+would be to store the user object acquired from database in an authentication
+middleware. Keys added are accessible to all later middleware as well as
+the handler over the duration of the request.
+
+Custom context is reserved for applications and extensions. Sanic itself makes
+no use of it.
+
+Listeners
+---------
+
+If you want to execute startup/teardown code as your server starts or closes, you can use the following listeners:
+
+- `before_server_start`
+- `after_server_start`
+- `before_server_stop`
+- `after_server_stop`
+
+These listeners are implemented as decorators on functions which accept the app object as well as the asyncio loop.
+
+For example:
+
+.. code-block:: python

+
+    @app.listener('after_server_stop')
+    async def close_db(app, loop):

+

-# Request Data
-
-When an endpoint receives a HTTP request, the route function is passed a
-`Request` object.
-
-The following variables are accessible as properties on `Request` objects:
-
-- `json` (any) - JSON body
-
-  ```python
-  from sanic.response import json
-
-  @app.route("/json")
-  def post_json(request):
-      return json({ "received": True, "message": request.json })
-  ```
-
-- `args` (dict) - Query string variables. A query string is the section of a
-  URL that resembles `?key1=value1&key2=value2`. If that URL were to be parsed,
-  the `args` dictionary would look like `{'key1': ['value1'], 'key2': ['value2']}`.
-  The request's `query_string` variable holds the unparsed string value.
-
-  ```python
-  from sanic.response import json
-
-  @app.route("/query_string")
-  def query_string(request):
-      return json({ "parsed": True, "args": request.args, "url": request.url, "query_string": request.query_string })
-  ```
-
-- `raw_args` (dict) - On many cases you would need to access the url arguments in
-  a less packed dictionary. For same previous URL `?key1=value1&key2=value2`, the
-  `raw_args` dictionary would look like `{'key1': 'value1', 'key2': 'value2'}`.
-
-- `files` (dictionary of `File` objects) - List of files that have a name, body, and type
-
-  ```python
-  from sanic.response import json
-
-  @app.route("/files")
-  def post_json(request):
-      test_file = request.files.get('test')
-
-      file_parameters = {
-          'body': test_file.body,
-          'name': test_file.name,
-          'type': test_file.type,
-      }
-
-      return json({ "received": True, "file_names": request.files.keys(), "test_file_parameters": file_parameters })
-  ```
-
-- `form` (dict) - Posted form variables.
-
-  ```python
-  from sanic.response import json
-
-  @app.route("/form")
-  def post_json(request):
-      return json({ "received": True, "form_data": request.form, "test": request.form.get('test') })
-  ```
-
-- `body` (bytes) - Posted raw body. This property allows retrieval of the
-  request's raw data, regardless of content type.
-
-  ```python
-  from sanic.response import text
-
-  @app.route("/users", methods=["POST",])
-  def create_user(request):
-      return text("You are trying to create a user with the following POST: %s" % request.body)
-  ```
-
-- `headers` (dict) - A case-insensitive dictionary that contains the request headers.
-
-- `method` (str) - HTTP method of the request (ie `GET`, `POST`).
-
-- `ip` (str) - IP address of the requester.
-
-- `port` (str) - Port address of the requester.
-
-- `socket` (tuple) - (IP, port) of the requester.
-
-- `app` - a reference to the Sanic application object that is handling this request. This is useful when inside blueprints or other handlers in modules that do not have access to the global `app` object.
-
-  ```python
-  from sanic.response import json
-  from sanic import Blueprint
-
-  bp = Blueprint('my_blueprint')
-
-  @bp.route('/')
-  async def bp_root(request):
-      if request.app.config['DEBUG']:
-          return json({'status': 'debug'})
-      else:
-          return json({'status': 'production'})
-
-  ```
-- `url`: The full URL of the request, ie: `http://localhost:8000/posts/1/?foo=bar`
-- `scheme`: The URL scheme associated with the request: `http` or `https`
-- `host`: The host associated with the request: `localhost:8080`
-- `path`: The path of the request: `/posts/1/`
-- `query_string`: The query string of the request: `foo=bar` or a blank string `''`
-- `uri_template`: Template for matching route handler: `/posts/<id>/`
-- `token`: The value of Authorization header: `Basic YWRtaW46YWRtaW4=`
-
-
-## Accessing values using `get` and `getlist`
-
-The request properties which return a dictionary actually return a subclass of
-`dict` called `RequestParameters`. The key difference when using this object is
-the distinction between the `get` and `getlist` methods.
-
-- `get(key, default=None)` operates as normal, except that when the value of
-  the given key is a list, *only the first item is returned*.
-- `getlist(key, default=None)` operates as normal, *returning the entire list*.
-
-```python
-from sanic.request import RequestParameters
-
-args = RequestParameters()
-args['titles'] = ['Post 1', 'Post 2']
-
-args.get('titles') # => 'Post 1'
-
-args.getlist('titles') # => ['Post 1', 'Post 2']

+.. code-block:: python
+
+    from sanic.response import json
+
+    @app.route("/json")
+    def post_json(request):
+      return json({ "received": True, "message": request.json })
+
+
+- `args` (dict) - Query string variables. A query string is the section of a
+  URL that resembles ``?key1=value1&key2=value2``.
+If that URL were to be parsed, the `args` dictionary would look like `{'key1': ['value1'], 'key2': ['value2']}`.
+The request's `query_string` variable holds the unparsed string value. Property is providing the default parsing
+strategy. If you would like to change it look to the section below (`Changing the default parsing rules of the queryset`).
+
+.. code-block:: python
+
+    from sanic.response import json
+
+    @app.route("/query_string")
+    def query_string(request):
+      return json({ "parsed": True, "args": request.args, "url": request.url, "query_string": request.query_string })
+
+- `query_args` (list) - On many cases you would need to access the url arguments in
+  a less packed form. `query_args` is the list of `(key, value)` tuples.
+Property is providing the default parsing strategy. If you would like to change it look to the section below
+(`Changing the default parsing rules of the queryset`). For the same previous URL queryset `?key1=value1&key2=value2`,
+the `query_args` list would look like `[('key1', 'value1'), ('key2', 'value2')]`. And in case of the multiple params
+with the same key like `?key1=value1&key2=value2&key1=value3` the `query_args` list would look like
+`[('key1', 'value1'), ('key2', 'value2'), ('key1', 'value3')]`.

+    }
+
+- `raw_args` contains only the first entry of `key1`. Will be deprecated in the future versions.
+
+- `files` (dictionary of `File` objects) - List of files that have a name, body, and type
+
+.. code-block:: python

+
+    @app.route("/files")
+    def post_json(request):

+
+- `form` (dict) - Posted form variables.
+
+.. code-block:: python
+
+    from sanic.response import json
+
+    @app.route("/form")
+    def post_json(request):
+      return json({ "received": True, "form_data": request.form, "test": request.form.get('test') })
+
+- `body` (bytes) - Posted raw body. This property allows retrieval of the
+  request's raw data, regardless of content type.
+
+.. code-block:: python
+
+  from sanic.response import text
+
+  @app.route("/users", methods=["POST",])
+  def create_user(request):
+      return text("You are trying to create a user with the following POST: %s" % request.body)
+
+
+- `headers` (dict) - A case-insensitive dictionary that contains the request headers.
+
+- `method` (str) - HTTP method of the request (ie `GET`, `POST`).
+
+- `ip` (str) - IP address of the requester.
+
+- `port` (str) - Port address of the requester.
+
+- `socket` (tuple) - (IP, port) of the requester.
+
+- `app` - a reference to the Sanic application object that is handling this request. This is useful when inside blueprints or other handlers in modules that do not have access to the global `app` object.
+
+.. code-block:: python
+
+  from sanic.response import json
+  from sanic import Blueprint
+
+  bp = Blueprint('my_blueprint')
+
+  @bp.route('/')
+  async def bp_root(request):
+      if request.app.config['DEBUG']:
+          return json({'status': 'debug'})
+      else:
+          return json({'status': 'production'})
+
+- `url`: The full URL of the request, ie: `http://localhost:8000/posts/1/?foo=bar`
+- `scheme`: The URL scheme associated with the request: 'http|https|ws|wss' or arbitrary value given by the headers.
+- `host`: The host associated with the request(which in the `Host` header): `localhost:8080`
+- `server_name`: The hostname of the server, without port number. the value is seeked in this order: `config.SERVER_NAME`, `x-forwarded-host` header, :func:`Request.host`
+- `server_port`: Like `server_name`. Seeked in this order: `x-forwarded-port` header, :func:`Request.host`, actual port used by the transport layer socket.
+- `path`: The path of the request: `/posts/1/`
+- `query_string`: The query string of the request: `foo=bar` or a blank string `''`
+- `uri_template`: Template for matching route handler: `/posts/<id>/`
+- `token`: The value of Authorization header: `Basic YWRtaW46YWRtaW4=`
+
+- `url_for`: Just like `sanic.Sanic.url_for`, but automatically determine `scheme` and `netloc` base on the request. Since this method is aiming to generate correct schema & netloc, `_external` is implied.
+
+
+Changing the default parsing rules of the queryset
+--------------------------------------------------
+
+The default parameters that are using internally in `args` and `query_args` properties to parse queryset:
+
+- `keep_blank_values` (bool): `False` - flag indicating whether blank values in
+  percent-encoded queries should be treated as blank strings.
+  A true value indicates that blanks should be retained as blank
+  strings.  The default false value indicates that blank values
+  are to be ignored and treated as if they were  not included.
+- `strict_parsing` (bool): `False` - flag indicating what to do with parsing errors. If
+  false (the default), errors are silently ignored. If true,
+  errors raise a ValueError exception.
+- `encoding` and `errors` (str): 'utf-8' and 'replace' - specify how to decode percent-encoded sequences
+  into Unicode characters, as accepted by the bytes.decode() method.
+
+If you would like to change that default parameters you could call `get_args` and `get_query_args` methods
+with the new values.
+
+For the queryset `/?test1=value1&test2=&test3=value3`:
+
+.. code-block:: python
+
+    from sanic.response import json
+
+    @app.route("/query_string")
+    def query_string(request):
+        args_with_blank_values = request.get_args(keep_blank_values=True)
+        return json({
+            "parsed": True,
+            "url": request.url,
+            "args_with_blank_values": args_with_blank_values,
+            "query_string": request.query_string
+        })
+
+The output will be:
+
+.. code-block:: JSON
+
+    {
+        "parsed": true,
+        "url": "http:\/\/0.0.0.0:8000\/query_string?test1=value1&test2=&test3=value3",
+        "args_with_blank_values": {"test1": ["value1"], "test2": "", "test3": ["value3"]},
+        "query_string": "test1=value1&test2=&test3=value3"
+    }
+
+Accessing values using `get` and `getlist`
+------------------------------------------
+
+The `request.args` returns a subclass of `dict` called `RequestParameters`. 
+The key difference when using this object is the distinction between the `get` and `getlist` methods.
+
+- `get(key, default=None)` operates as normal, except that when the value of
+  the given key is a list, *only the first item is returned*.
+- `getlist(key, default=None)` operates as normal, *returning the entire list*.
+
+.. code-block:: python
+
+    from sanic.request import RequestParameters
+
+    args = RequestParameters()
+    args['titles'] = ['Post 1', 'Post 2']
+
+    args.get('titles') # => 'Post 1'
+
+    args.getlist('titles') # => ['Post 1', 'Post 2']
+
+.. code-block:: python
+    from sanic import Sanic
+    from sanic.response import json
+
+    app = Sanic(name="example")
+
+    @app.route("/")
+    def get_handler(request):
+        return json({
+            "p1": request.args.getlist("p1")
+        })
+        
+Accessing the handler name with the request.endpoint attribute
+--------------------------------------------------------------
+
+The `request.endpoint` attribute holds the handler's name. For instance, the below
+route will return "hello".
+
+.. code-block:: python
+
+    from sanic.response import text
+    from sanic import Sanic
+
+    app = Sanic()
+
+    @app.get("/")
+    def hello(request):
+        return text(request.endpoint)
+
+Or, with a blueprint it will be include both, separated by a period. For example, the below route would return foo.bar:
+
+.. code-block:: python
+
+    from sanic import Sanic
+    from sanic import Blueprint
+    from sanic.response import text
+
+
+    app = Sanic(__name__)
+    blueprint = Blueprint('foo')
+
+    @blueprint.get('/')
+    async def bar(request):
+        return text(request.endpoint)
+
+    app.blueprint(blueprint)
+
+    app.run(host="0.0.0.0", port=8000, debug=True)

-# Routing
-
-Routing allows the user to specify handler functions for different URL endpoints.
-
-A basic route looks like the following, where `app` is an instance of the
-`Sanic` class:
-
-```python
-from sanic.response import json
-
-@app.route("/")
-async def test(request):
-    return json({ "hello": "world" })
-```
-
-When the url `http://server.url/` is accessed (the base url of the server), the
-final `/` is matched by the router to the handler function, `test`, which then
-returns a JSON object.
-
-Sanic handler functions must be defined using the `async def` syntax, as they
-are asynchronous functions.
-
-## Request parameters
-
-Sanic comes with a basic router that supports request parameters.
-
-To specify a parameter, surround it with angle quotes like so: `<PARAM>`.
-Request parameters will be passed to the route handler functions as keyword
-arguments.
-
-```python
-from sanic.response import text
-
-@app.route('/tag/<tag>')
-async def tag_handler(request, tag):
-	return text('Tag - {}'.format(tag))
-```
-
-To specify a type for the parameter, add a `:type` after the parameter name,
-inside the quotes. If the parameter does not match the specified type, Sanic
-will throw a `NotFound` exception, resulting in a `404: Page not found` error
-on the URL.
-
-```python
-from sanic.response import text
-
-@app.route('/number/<integer_arg:int>')
-async def integer_handler(request, integer_arg):
-	return text('Integer - {}'.format(integer_arg))
-
-@app.route('/number/<number_arg:number>')
-async def number_handler(request, number_arg):
-	return text('Number - {}'.format(number_arg))
-
-@app.route('/person/<name:[A-z]+>')
-async def person_handler(request, name):
-	return text('Person - {}'.format(name))
-
-@app.route('/folder/<folder_id:[A-z0-9]{0,4}>')
-async def folder_handler(request, folder_id):
-	return text('Folder - {}'.format(folder_id))
-
-```
-
-## HTTP request types
-
-By default, a route defined on a URL will be available for only GET requests to that URL.
-However, the `@app.route` decorator accepts an optional parameter, `methods`,
-which allows the handler function to work with any of the HTTP methods in the list.
-
-```python
-from sanic.response import text
-
-@app.route('/post', methods=['POST'])
-async def post_handler(request):
-	return text('POST request - {}'.format(request.json))
-
-@app.route('/get', methods=['GET'])
-async def get_handler(request):
-	return text('GET request - {}'.format(request.args))
-
-```
-
-There is also an optional `host` argument (which can be a list or a string). This restricts a route to the host or hosts provided. If there is a also a route with no host, it will be the default.
-
-```python
-@app.route('/get', methods=['GET'], host='example.com')
-async def get_handler(request):
-	return text('GET request - {}'.format(request.args))
-
-# if the host header doesn't match example.com, this route will be used
-@app.route('/get', methods=['GET'])
-async def get_handler(request):
-	return text('GET request in default - {}'.format(request.args))
-```
-
-There are also shorthand method decorators:
-
-```python
-from sanic.response import text
-
-@app.post('/post')
-async def post_handler(request):
-	return text('POST request - {}'.format(request.json))
-
-@app.get('/get')
-async def get_handler(request):
-	return text('GET request - {}'.format(request.args))
-
-```
-## The `add_route` method
-
-As we have seen, routes are often specified using the `@app.route` decorator.
-However, this decorator is really just a wrapper for the `app.add_route`
-method, which is used as follows:
-
-```python
-from sanic.response import text
-
-# Define the handler functions
-async def handler1(request):
-	return text('OK')
-
-async def handler2(request, name):
-	return text('Folder - {}'.format(name))
-
-async def person_handler2(request, name):
-	return text('Person - {}'.format(name))
-
-# Add each handler function as a route
-app.add_route(handler1, '/test')
-app.add_route(handler2, '/folder/<name>')
-app.add_route(person_handler2, '/person/<name:[A-z]>', methods=['GET'])
-```
-
-## URL building with `url_for`
-
-Sanic provides a `url_for` method, to generate URLs based on the handler method name. This is useful if you want to avoid hardcoding url paths into your app; instead, you can just reference the handler name. For example:
-
-```python
-from sanic.response import redirect
-
-@app.route('/')
-async def index(request):
-    # generate a URL for the endpoint `post_handler`
-    url = app.url_for('post_handler', post_id=5)
-    # the URL is `/posts/5`, redirect to it
-    return redirect(url)    
-
-@app.route('/posts/<post_id>')
-async def post_handler(request, post_id):
-    return text('Post - {}'.format(post_id))
-```
-
-Other things to keep in mind when using `url_for`:
-
-- Keyword arguments passed to `url_for` that are not request parameters will be included in the URL's query string. For example:
-```python
-url = app.url_for('post_handler', post_id=5, arg_one='one', arg_two='two')
-# /posts/5?arg_one=one&arg_two=two
-```
-- Multivalue argument can be passed to `url_for`. For example:
-```python
-url = app.url_for('post_handler', post_id=5, arg_one=['one', 'two'])
-# /posts/5?arg_one=one&arg_one=two
-```
-- Also some special arguments (`_anchor`, `_external`, `_scheme`, `_method`, `_server`) passed to `url_for` will have special url building (`_method` is not support now and will be ignored). For example:
-```python
-url = app.url_for('post_handler', post_id=5, arg_one='one', _anchor='anchor')
-# /posts/5?arg_one=one#anchor
-
-url = app.url_for('post_handler', post_id=5, arg_one='one', _external=True)
-# //server/posts/5?arg_one=one
-# _external requires passed argument _server or SERVER_NAME in app.config or url will be same as no _external
-
-url = app.url_for('post_handler', post_id=5, arg_one='one', _scheme='http', _external=True)
-# http://server/posts/5?arg_one=one
-# when specifying _scheme, _external must be True
-
-# you can pass all special arguments one time
-url = app.url_for('post_handler', post_id=5, arg_one=['one', 'two'], arg_two=2, _anchor='anchor', _scheme='http', _external=True, _server='another_server:8888')
-# http://another_server:8888/posts/5?arg_one=one&arg_one=two&arg_two=2#anchor
-```
-- All valid parameters must be passed to `url_for` to build a URL. If a parameter is not supplied, or if a parameter does not match the specified type, a `URLBuildError` will be thrown.
-
-## WebSocket routes
-
-Routes for the WebSocket protocol can be defined with the `@app.websocket`
-decorator:
-
-```python
-@app.websocket('/feed')
-async def feed(request, ws):
-    while True:
-        data = 'hello!'
-        print('Sending: ' + data)
-        await ws.send(data)
-        data = await ws.recv()
-        print('Received: ' + data)
-```
-
-Alternatively, the `app.add_websocket_route` method can be used instead of the
-decorator:
-
-```python
-async def feed(request, ws):
-    pass
-
-app.add_websocket_route(my_websocket_handler, '/feed')
-```
-
-Handlers for a WebSocket route are passed the request as first argument, and a
-WebSocket protocol object as second argument. The protocol object has `send`
-and `recv` methods to send and receive data respectively.
-
-WebSocket support requires the [websockets](https://github.com/aaugustin/websockets)
-package by Aymeric Augustin.

-## About `strict_slashes`
-
-You can make `routes` strict to trailing slash or not, it's configurable.
-
-```python
-
-# provide default strict_slashes value for all routes
-app = Sanic('test_route_strict_slash', strict_slashes=True)
-
-# you can also overwrite strict_slashes value for specific route
-@app.get('/get', strict_slashes=False)
-def handler(request):
-    return text('OK')
-
-# It also works for blueprints
-bp = Blueprint('test_bp_strict_slash', strict_slashes=True)
-
-@bp.get('/bp/get', strict_slashes=False)
-def handler(request):
-    return text('OK')
-
-app.blueprint(bp)
-```
-
-## User defined route name
-
-You can pass `name` to change the route name to avoid using the default name  (`handler.__name__`).
-
-```python
-
-app = Sanic('test_named_route')
-
-@app.get('/get', name='get_handler')
-def handler(request):
-    return text('OK')
-
-# then you need use `app.url_for('get_handler')`
-# instead of # `app.url_for('handler')`
-
-# It also works for blueprints
-bp = Blueprint('test_named_bp')
-
-@bp.get('/bp/get', name='get_handler')
-def handler(request):
-    return text('OK')
-
-app.blueprint(bp)
-
-# then you need use `app.url_for('test_named_bp.get_handler')`
-# instead of `app.url_for('test_named_bp.handler')`
-
-# different names can be used for same url with different methods
-
-@app.get('/test', name='route_test')
-def handler(request):
-    return text('OK')
-
-@app.post('/test', name='route_post')
-def handler2(request):
-    return text('OK POST')
-
-@app.put('/test', name='route_put')
-def handler3(request):
-    return text('OK PUT')
-
-# below url are the same, you can use any of them
-# '/test'
-app.url_for('route_test')
-# app.url_for('route_post')
-# app.url_for('route_put')
-
-# for same handler name with different methods
-# you need specify the name (it's url_for issue)
-@app.get('/get')
-def handler(request):
-    return text('OK')
-
-@app.post('/post', name='post_handler')
-def handler(request):
-    return text('OK')
-
-# then
-# app.url_for('handler') == '/get'
-# app.url_for('post_handler') == '/post'
-```
-
-## Build URL for static files
-
-You can use `url_for` for static file url building now.
-If it's for file directly, `filename` can be ignored.
-
-```python
-
-app = Sanic('test_static')
-app.static('/static', './static')
-app.static('/uploads', './uploads', name='uploads')
-app.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
-
-bp = Blueprint('bp', url_prefix='bp')
-bp.static('/static', './static')
-bp.static('/uploads', './uploads', name='uploads')
-bp.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
-app.blueprint(bp)
-
-# then build the url
-app.url_for('static', filename='file.txt') == '/static/file.txt'
-app.url_for('static', name='static', filename='file.txt') == '/static/file.txt'
-app.url_for('static', name='uploads', filename='file.txt') == '/uploads/file.txt'
-app.url_for('static', name='best_png') == '/the_best.png'
-
-# blueprint url building
-app.url_for('static', name='bp.static', filename='file.txt') == '/bp/static/file.txt'
-app.url_for('static', name='bp.uploads', filename='file.txt') == '/bp/uploads/file.txt'
-app.url_for('static', name='bp.best_png') == '/bp/static/the_best.png'

+Routing
+-------
+
+Routing allows the user to specify handler functions for different URL endpoints.
+
+A basic route looks like the following, where `app` is an instance of the
+`Sanic` class:
+
+.. code-block:: python
+
+    from sanic.response import json
+
+    @app.route("/")
+    async def test(request):
+        return json({ "hello": "world" })
+
+When the url `http://server.url/` is accessed (the base url of the server), the
+final `/` is matched by the router to the handler function, `test`, which then
+returns a JSON object.
+
+Sanic handler functions must be defined using the `async def` syntax, as they
+are asynchronous functions.
+
+Request parameters
+==================
+
+Sanic comes with a basic router that supports request parameters.
+
+To specify a parameter, surround it with angle quotes like so: `<PARAM>`.
+Request parameters will be passed to the route handler functions as keyword
+arguments.
+
+.. code-block:: python
+
+    from sanic.response import text
+
+    @app.route('/tag/<tag>')
+    async def tag_handler(request, tag):
+        return text('Tag - {}'.format(tag))
+
+To specify a type for the parameter, add a `:type` after the parameter name,
+inside the quotes. If the parameter does not match the specified type, Sanic
+will throw a `NotFound` exception, resulting in a `404: Page not found` error
+on the URL.
+
+Supported types
+~~~~~~~~~~~~~~~
+
+* `string`
+    * "Bob"
+    * "Python 3"
+* `int`
+    * 10
+    * 20
+    * 30
+    * -10
+    * (No floats work here)
+* `number`
+    * 1
+    * 1.5
+    * 10
+    * -10
+* `alpha`
+    * "Bob"
+    * "Python"
+    * (If it contains a symbol or a non alphanumeric character it will fail)
+* `path`
+    * "hello"
+    * "hello.text"
+    * "hello world"
+* `uuid`
+    * 123a123a-a12a-1a1a-a1a1-1a12a1a12345 (UUIDv4 Support)
+* `regex expression`
+
+If no type is set then a string is expected. The argument given to the function will always be a string, independent of the type.
+
+.. code-block:: python
+
+    from sanic.response import text
+
+    @app.route('/string/<string_arg:string>')
+    async def string_handler(request, string_arg):
+        return text('String - {}'.format(string_arg))
+
+    @app.route('/int/<integer_arg:int>')
+    async def integer_handler(request, integer_arg):
+        return text('Integer - {}'.format(integer_arg))
+
+    @app.route('/number/<number_arg:number>')
+    async def number_handler(request, number_arg):
+        return text('Number - {}'.format(number_arg))
+
+    @app.route('/alpha/<alpha_arg:alpha>')
+    async def number_handler(request, alpha_arg):
+        return text('Alpha - {}'.format(alpha_arg))
+
+    @app.route('/path/<path_arg:path>')
+    async def number_handler(request, path_arg):
+        return text('Path - {}'.format(path_arg))
+
+    @app.route('/uuid/<uuid_arg:uuid>')
+    async def number_handler(request, uuid_arg):
+        return text('Uuid - {}'.format(uuid_arg))
+
+    @app.route('/person/<name:[A-z]+>')
+    async def person_handler(request, name):
+        return text('Person - {}'.format(name))
+
+    @app.route('/folder/<folder_id:[A-z0-9]{0,4}>')
+    async def folder_handler(request, folder_id):
+        return text('Folder - {}'.format(folder_id))
+
+.. warning::
+
+    `str` is not a valid type tag. If you want `str` recognition then you must use `string`
+
+HTTP request types
+==================
+
+By default, a route defined on a URL will be available for only GET requests to that URL.
+However, the `@app.route` decorator accepts an optional parameter, `methods`,
+which allows the handler function to work with any of the HTTP methods in the list.
+
+.. code-block:: python
+
+    from sanic.response import text
+
+    @app.route('/post', methods=['POST'])
+    async def post_handler(request):
+        return text('POST request - {}'.format(request.json))
+
+    @app.route('/get', methods=['GET'])
+    async def get_handler(request):
+        return text('GET request - {}'.format(request.args))
+
+There is also an optional `host` argument (which can be a list or a string). This restricts a route to the host or hosts provided. If there is a also a route with no host, it will be the default.
+
+.. code-block:: python
+
+    @app.route('/get', methods=['GET'], host='example.com')
+    async def get_handler(request):
+        return text('GET request - {}'.format(request.args))
+
+    # if the host header doesn't match example.com, this route will be used
+    @app.route('/get', methods=['GET'])
+    async def get_handler(request):
+        return text('GET request in default - {}'.format(request.args))
+
+There are also shorthand method decorators:
+
+.. code-block:: python
+
+    from sanic.response import text
+
+    @app.post('/post')
+    async def post_handler(request):
+        return text('POST request - {}'.format(request.json))
+
+    @app.get('/get')
+    async def get_handler(request):
+        return text('GET request - {}'.format(request.args))
+
+The `add_route` method
+======================
+
+As we have seen, routes are often specified using the `@app.route` decorator.
+However, this decorator is really just a wrapper for the `app.add_route`
+method, which is used as follows:
+
+.. code-block:: python
+
+    from sanic.response import text
+
+    # Define the handler functions
+    async def handler1(request):
+        return text('OK')
+
+    async def handler2(request, name):
+        return text('Folder - {}'.format(name))
+
+    async def person_handler2(request, name):
+        return text('Person - {}'.format(name))
+
+    # Add each handler function as a route
+    app.add_route(handler1, '/test')
+    app.add_route(handler2, '/folder/<name>')
+    app.add_route(person_handler2, '/person/<name:[A-z]>', methods=['GET'])
+
+URL building with `url_for`
+===========================
+
+Sanic provides a `url_for` method, to generate URLs based on the handler method name. This is useful if you want to avoid hardcoding url paths into your app; instead, you can just reference the handler name. For example:
+
+.. code-block:: python
+
+    from sanic.response import redirect
+
+    @app.route('/')
+    async def index(request):
+        # generate a URL for the endpoint `post_handler`
+        url = app.url_for('post_handler', post_id=5)
+        # the URL is `/posts/5`, redirect to it
+        return redirect(url)
+
+    @app.route('/posts/<post_id>')
+    async def post_handler(request, post_id):
+        return text('Post - {}'.format(post_id))
+
+Other things to keep in mind when using `url_for`:
+
+- Keyword arguments passed to `url_for` that are not request parameters will be included in the URL's query string. For example:
+
+.. code-block:: python
+
+    url = app.url_for('post_handler', post_id=5, arg_one='one', arg_two='two')
+    # /posts/5?arg_one=one&arg_two=two
+
+- Multivalue argument can be passed to `url_for`. For example:
+
+.. code-block:: python
+
+    url = app.url_for('post_handler', post_id=5, arg_one=['one', 'two'])
+    # /posts/5?arg_one=one&arg_one=two
+
+- Also some special arguments (`_anchor`, `_external`, `_scheme`, `_method`, `_server`) passed to `url_for` will have special url building (`_method` is not supported now and will be ignored). For example:
+
+.. code-block:: python
+
+    url = app.url_for('post_handler', post_id=5, arg_one='one', _anchor='anchor')
+    # /posts/5?arg_one=one#anchor
+
+    url = app.url_for('post_handler', post_id=5, arg_one='one', _external=True)
+    # //server/posts/5?arg_one=one
+    # _external requires you to pass an argument _server or set SERVER_NAME in app.config if not url will be same as no _external
+
+    url = app.url_for('post_handler', post_id=5, arg_one='one', _scheme='http', _external=True)
+    # http://server/posts/5?arg_one=one
+    # when specifying _scheme, _external must be True
+
+    # you can pass all special arguments at once
+    url = app.url_for('post_handler', post_id=5, arg_one=['one', 'two'], arg_two=2, _anchor='anchor', _scheme='http', _external=True, _server='another_server:8888')
+    # http://another_server:8888/posts/5?arg_one=one&arg_one=two&arg_two=2#anchor
+
+- All valid parameters must be passed to `url_for` to build a URL. If a parameter is not supplied, or if a parameter does not match the specified type, a `URLBuildError` will be raised.
+
+WebSocket routes
+================
+
+Routes for the WebSocket protocol can be defined with the `@app.websocket`
+decorator:
+
+.. code-block:: python
+
+    @app.websocket('/feed')
+    async def feed(request, ws):
+        while True:
+            data = 'hello!'
+            print('Sending: ' + data)
+            await ws.send(data)
+            data = await ws.recv()
+            print('Received: ' + data)
+
+Alternatively, the `app.add_websocket_route` method can be used instead of the
+decorator:
+
+.. code-block:: python
+
+    async def feed(request, ws):
+        pass
+
+    app.add_websocket_route(my_websocket_handler, '/feed')
+
+Handlers to a WebSocket route are invoked with the request as first argument, and a
+WebSocket protocol object as second argument. The protocol object has `send`
+and `recv` methods to send and receive data respectively.
+
+WebSocket support requires the `websockets <https://github.com/aaugustin/websockets>`_
+package by Aymeric Augustin.
+
+
+About `strict_slashes`
+======================
+
+You can make `routes` strict to trailing slash or not, it's configurable.
+
+.. code-block:: python
+
+    # provide default strict_slashes value for all routes
+    app = Sanic('test_route_strict_slash', strict_slashes=True)
+
+    # you can also overwrite strict_slashes value for specific route
+    @app.get('/get', strict_slashes=False)
+    def handler(request):
+        return text('OK')
+
+    # It also works for blueprints
+    bp = Blueprint('test_bp_strict_slash', strict_slashes=True)
+
+    @bp.get('/bp/get', strict_slashes=False)
+    def handler(request):
+        return text('OK')
+
+    app.blueprint(bp)
+
+The behavior of how the `strict_slashes` flag follows a defined hierarchy which decides if a specific route
+falls under the `strict_slashes` behavior.
+
+|    Route/
+|    ├──Blueprint/
+|       ├──Application/
+
+Above hierarchy defines how the `strict_slashes` flag will behave. The first non `None` value of the `strict_slashes`
+found in the above order will be applied to the route in question.
+
+.. code-block:: python
+
+    from sanic import Sanic, Blueprint
+    from sanic.response import text
+
+    app = Sanic("sample_strict_slashes", strict_slashes=True)
+
+    @app.get("/r1")
+    def r1(request):
+        return text("strict_slashes is applicable from App level")
+
+    @app.get("/r2", strict_slashes=False)
+    def r2(request):
+        return text("strict_slashes is not applicable due to  False value set in route level")
+
+    bp = Blueprint("bp", strict_slashes=False)
+
+    @bp.get("/r3", strict_slashes=True)
+    def r3(request):
+        return text("strict_slashes applicable from blueprint route level")
+
+    bp1 = Blueprint("bp1", strict_slashes=True)
+
+    @bp.get("/r4")
+    def r3(request):
+        return text("strict_slashes applicable from blueprint level")
+
+User defined route name
+=======================
+
+A custom route name can be used by passing a `name` argument while registering the route which will
+override the default route name generated using the `handler.__name__` attribute.
+
+.. code-block:: python
+
+    app = Sanic('test_named_route')
+
+    @app.get('/get', name='get_handler')
+    def handler(request):
+        return text('OK')
+
+    # then you need use `app.url_for('get_handler')`
+    # instead of # `app.url_for('handler')`
+
+    # It also works for blueprints
+    bp = Blueprint('test_named_bp')
+
+    @bp.get('/bp/get', name='get_handler')
+    def handler(request):
+        return text('OK')
+
+    app.blueprint(bp)
+
+    # then you need use `app.url_for('test_named_bp.get_handler')`
+    # instead of `app.url_for('test_named_bp.handler')`
+
+    # different names can be used for same url with different methods
+
+    @app.get('/test', name='route_test')
+    def handler(request):
+        return text('OK')
+
+    @app.post('/test', name='route_post')
+    def handler2(request):
+        return text('OK POST')
+
+    @app.put('/test', name='route_put')
+    def handler3(request):
+        return text('OK PUT')
+
+    # below url are the same, you can use any of them
+    # '/test'
+    app.url_for('route_test')
+    # app.url_for('route_post')
+    # app.url_for('route_put')
+
+    # for same handler name with different methods
+    # you need specify the name (it's url_for issue)
+    @app.get('/get')
+    def handler(request):
+        return text('OK')
+
+    @app.post('/post', name='post_handler')
+    def handler(request):
+        return text('OK')
+
+    # then
+    # app.url_for('handler') == '/get'
+    # app.url_for('post_handler') == '/post'
+
+Build URL for static files
+==========================
+
+Sanic supports using `url_for` method to build static file urls. In case if the static url
+is pointing to a directory, `filename` parameter to the `url_for` can be ignored.   q
+
+.. code-block:: python
+
+    app = Sanic('test_static')
+    app.static('/static', './static')
+    app.static('/uploads', './uploads', name='uploads')
+    app.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')

+    bp.static('/uploads', './uploads', name='uploads')
+    bp.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
+    app.blueprint(bp)
+
+    # then build the url
+    app.url_for('static', filename='file.txt') == '/static/file.txt'
+    app.url_for('static', name='static', filename='file.txt') == '/static/file.txt'
+    app.url_for('static', name='uploads', filename='file.txt') == '/uploads/file.txt'

-# Static Files
-
-Static files and directories, such as an image file, are served by Sanic when
-registered with the `app.static()` method. The method takes an endpoint URL and a
-filename. The file specified will then be accessible via the given endpoint.
-
-```python
-from sanic import Sanic
-from sanic.blueprints import Blueprint
-
-app = Sanic(__name__)
-
-# Serves files from the static folder to the URL /static
-app.static('/static', './static')
-# use url_for to build the url, name defaults to 'static' and can be ignored
-app.url_for('static', filename='file.txt') == '/static/file.txt'
-app.url_for('static', name='static', filename='file.txt') == '/static/file.txt'
-
-# Serves the file /home/ubuntu/test.png when the URL /the_best.png
-# is requested
-app.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
-
-# you can use url_for to build the static file url
-# you can ignore name and filename parameters if you don't define it
-app.url_for('static', name='best_png') == '/the_best.png'
-app.url_for('static', name='best_png', filename='any') == '/the_best.png'
-
-# you need define the name for other static files
-app.static('/another.png', '/home/ubuntu/another.png', name='another')
-app.url_for('static', name='another') == '/another.png'
-app.url_for('static', name='another', filename='any') == '/another.png'
-
-# also, you can use static for blueprint
-bp = Blueprint('bp', url_prefix='/bp')
-bp.static('/static', './static')
-
-# servers the file directly
-bp.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
-app.blueprint(bp)
-
-app.url_for('static', name='bp.static', filename='file.txt') == '/bp/static/file.txt'
-app.url_for('static', name='bp.best_png') == '/bp/test_best.png'
-
-app.run(host="0.0.0.0", port=8000)
-```
-
-> **Note:** Sanic does not provide directory index when you serve a static directory.
-
-## Virtual Host
-
-The `app.static()` method also support **virtual host**. You can serve your static files with spefic **virtual host** with `host` argument. For example:
-
-```python
-from sanic import Sanic
-
-app = Sanic(__name__)
-
-app.static('/static', './static')
-app.static('/example_static', './example_static', host='www.example.com')
-```
-
-## Streaming Large File
-
-In some cases, you might server large file(ex: videos, images, etc.) with Sanic. You can choose to use **streaming file** rather than download directly.
-
-Here is an example:
-```python
-from sanic import Sanic
-
-app = Sanic(__name__)
-
-app.static('/large_video.mp4', '/home/ubuntu/large_video.mp4', stream_large_files=True)
-```
-
-When `stream_large_files` is `True`, Sanic will use `file_stream()` instead of `file()` to serve static files. This will use **1KB** as the default chunk size. And, if needed, you can also use a custom chunk size. For example:
-```python
-from sanic import Sanic
-
-app = Sanic(__name__)
-
-chunk_size = 1024 * 1024 * 8 # Set chunk size to 8KB
-app.static('/large_video.mp4', '/home/ubuntu/large_video.mp4', stream_large_files=chunk_size)

+Static Files
+============
+
+Static files and directories, such as an image file, are served by Sanic when
+registered with the `app.static()` method. The method takes an endpoint URL and a
+filename. The file specified will then be accessible via the given endpoint.
+
+.. code-block:: python
+
+    from sanic import Sanic
+    from sanic.blueprints import Blueprint
+
+    app = Sanic(__name__)
+
+    # Serves files from the static folder to the URL /static
+    app.static('/static', './static')
+    # use url_for to build the url, name defaults to 'static' and can be ignored
+    app.url_for('static', filename='file.txt') == '/static/file.txt'
+    app.url_for('static', name='static', filename='file.txt') == '/static/file.txt'
+
+    # Serves the file /home/ubuntu/test.png when the URL /the_best.png
+    # is requested
+    app.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
+
+    # you can use url_for to build the static file url
+    # you can ignore name and filename parameters if you don't define it
+    app.url_for('static', name='best_png') == '/the_best.png'
+    app.url_for('static', name='best_png', filename='any') == '/the_best.png'
+
+    # you need define the name for other static files
+    app.static('/another.png', '/home/ubuntu/another.png', name='another')
+    app.url_for('static', name='another') == '/another.png'
+    app.url_for('static', name='another', filename='any') == '/another.png'
+
+    # also, you can use static for blueprint
+    bp = Blueprint('bp', url_prefix='/bp')
+    bp.static('/static', './static')
+
+    # specify a different content_type for your files
+    # such as adding 'charset'
+    app.static('/', '/public/index.html', content_type="text/html; charset=utf-8")
+
+    # servers the file directly
+    bp.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
+    app.blueprint(bp)
+
+    app.url_for('static', name='bp.static', filename='file.txt') == '/bp/static/file.txt'
+    app.url_for('static', name='bp.best_png') == '/bp/test_best.png'
+
+    app.run(host="0.0.0.0", port=8000)
+
+> **Note:** Sanic does not provide directory index when you serve a static directory.
+
+Virtual Host
+------------
+
+The `app.static()` method also support **virtual host**. You can serve your static files with specific **virtual host** with `host` argument. For example:
+
+.. code-block:: python
+
+    from sanic import Sanic
+
+    app = Sanic(__name__)
+
+    app.static('/static', './static')
+    app.static('/example_static', './example_static', host='www.example.com')
+
+Streaming Large File
+--------------------
+
+In some cases, you might server large file(ex: videos, images, etc.) with Sanic. You can choose to use **streaming file** rather than download directly.
+
+Here is an example:
+
+.. code-block:: python
+
+    from sanic import Sanic
+
+    app = Sanic(__name__)
+
+    app.static('/large_video.mp4', '/home/ubuntu/large_video.mp4', stream_large_files=True)
+
+When `stream_large_files` is `True`, Sanic will use `file_stream()` instead of `file()` to serve static files. This will use **1KB** as the default chunk size. And, if needed, you can also use a custom chunk size. For example:
+
+.. code-block:: python
+
+    from sanic import Sanic
+
+    app = Sanic(__name__)
+
+    chunk_size = 1024 * 1024 * 8 # Set chunk size to 8KB
+    app.static('/large_video.mp4', '/home/ubuntu/large_video.mp4', stream_large_files=chunk_size)

-## Response Streaming
-
-Sanic allows you to stream content to the client with the `stream` method. This method accepts a coroutine callback which is passed a `StreamingHTTPResponse` object that is written to. A simple example is like follows:
-
-```python
-from sanic import Sanic
-from sanic.response import stream
-
-app = Sanic(__name__)
-
-@app.route("/")
-async def test(request):
-    async def sample_streaming_fn(response):
-        await response.write('foo,')
-        await response.write('bar')
-
-    return stream(sample_streaming_fn, content_type='text/csv')
-```
-
-This is useful in situations where you want to stream content to the client that originates in an external service, like a database. For example, you can stream database records to the client with the asynchronous cursor that `asyncpg` provides:
-
-```python
-@app.route("/")
-async def index(request):
-    async def stream_from_db(response):
-        conn = await asyncpg.connect(database='test')
-        async with conn.transaction():
-            async for record in conn.cursor('SELECT generate_series(0, 10)'):
-                await response.write(record[0])
-
-    return stream(stream_from_db)

+
+        return stream(stream_from_db)
+
+If a client supports HTTP/1.1, Sanic will use `chunked transfer encoding <https://en.wikipedia.org/wiki/Chunked_transfer_encoding>`_; you can explicitly enable or disable it using `chunked` option of the `stream` function.
+
+File Streaming
+--------------
+
+Sanic provides `sanic.response.file_stream` function that is useful when you want to send a large file. It returns a `StreamingHTTPResponse` object and will use chunked transfer encoding by default; for this reason Sanic doesn't add `Content-Length` HTTP header in the response. If you want to use this header, you can disable chunked transfer encoding and add it manually:
+
+.. code-block:: python
+
+    from aiofiles import os as async_os
+    from sanic.response import file_stream
+
+    @app.route("/")
+    async def index(request):
+        file_path = "/srv/www/whatever.png"
+
+        file_stat = await async_os.stat(file_path)
+        headers = {"Content-Length": str(file_stat.st_size)}
+
+        return await file_stream(
+            file_path,
+            headers=headers,
+            chunked=False,
+        )

-# Testing
-
-Sanic endpoints can be tested locally using the `test_client` object, which
-depends on the additional [aiohttp](https://aiohttp.readthedocs.io/en/stable/)
-library. 
-
-The `test_client` exposes `get`, `post`, `put`, `delete`, `patch`, `head` and `options` methods
-for you to run against your application. A simple example (using pytest) is like follows:
-
-```python
-# Import the Sanic app, usually created with Sanic(__name__)
-from external_server import app
-
-def test_index_returns_200():
-    request, response = app.test_client.get('/')

-
-def test_index_put_not_allowed():
-    request, response = app.test_client.put('/')
-    assert response.status == 405
-```
-
-Internally, each time you call one of the `test_client` methods, the Sanic app is run at `127.0.0.1:42101` and 
-your test request is executed against your application, using `aiohttp`. 
-
-The `test_client` methods accept the following arguments and keyword arguments:
-
-- `uri` *(default `'/'`)* A string representing the URI to test.
-- `gather_request` *(default `True`)* A boolean which determines whether the
-  original request will be returned by the function. If set to `True`, the
-  return value is a tuple of `(request, response)`, if `False` only the
-  response is returned.
-- `server_kwargs` *(default `{}`) a dict of additional arguments to pass into `app.run` before the test request is run.
-- `debug` *(default `False`)* A boolean which determines whether to run the server in debug mode.
-
-The function further takes the `*request_args` and `**request_kwargs`, which are passed directly to the aiohttp ClientSession request.
-
-For example, to supply data to a GET request, you would do the following:
-
-```python
-def test_get_request_includes_data():
-    params = {'key1': 'value1', 'key2': 'value2'}
-    request, response = app.test_client.get('/', params=params)

+Testing

+
+If you need to test using a free unpriveleged port chosen by the kernel
