+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+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;

+        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.

-Nginx Deployment
-================
-
-Introduction
-~~~~~~~~~~~~
-
-Although Sanic can be run directly on Internet, it may be useful to use a proxy
-server such as Nginx in front of it. This is particularly useful for running
-multiple virtual hosts on the same IP, serving NodeJS or other services beside
-a single Sanic app, and it also allows for efficient serving of static files.
-SSL and HTTP/2 are also easily implemented on such proxy.
-
-We are setting the Sanic app to serve only locally at `127.0.0.1:8000`, while the
-Nginx installation is responsible for providing the service to public Internet
-on domain `example.com`. Static files will be served from `/var/www/`.
-
-
-Proxied Sanic app
-~~~~~~~~~~~~~~~~~
-
-The app needs to be setup with a secret key used to identify a trusted proxy,
-so that real client IP and other information can be identified. This protects
-against anyone on the Internet sending fake headers to spoof their IP addresses
-and other details. Choose any random string and configure it both on the app
-and in Nginx config.
-
-.. code-block:: python
-
-    from sanic import Sanic
-    from sanic.response import text
-
-    app = Sanic("proxied_example")
-    app.config.FORWARDED_SECRET = "YOUR SECRET"
-
-    @app.get("/")
-    def index(request):
-        # This should display external (public) addresses:
-        return text(
-            f"{request.remote_addr} connected to {request.url_for('index')}\n"
-            f"Forwarded: {request.forwarded}\n"
-        )
-
-    if __name__ == '__main__':
-        app.run(host='127.0.0.1', port=8000, workers=8, access_log=False)
-
-Since this is going to be a system service, save your code to
-`/srv/sanicexample/sanicexample.py`.
-
-For testing, run your app in a terminal.
-
-
-Nginx configuration
-~~~~~~~~~~~~~~~~~~~
-
-Quite much configuration is required to allow fast transparent proxying, but
-for the most part these don't need to be modified, so bear with me.
-
-Upstream servers need to be configured in a separate `upstream` block to enable
-HTTP keep-alive, which can drastically improve performance, so we use this
-instead of directly providing an upstream address in `proxy_pass` directive. In
-this example, the upstream section is named by `server_name`, i.e. the public
-domain name, which then also gets passed to Sanic in the `Host` header. You may
-change the naming as you see fit. Multiple servers may also be provided for
-load balancing and failover.
-
-Change the two occurrences of `example.com` to your true domain name, and
-instead of `YOUR SECRET` use the secret you chose for your app.
-
-::
-
-    upstream example.com {
-      keepalive 100;
-      server 127.0.0.1:8000;
-      #server unix:/tmp/sanic.sock;
-    }
-
-    server {
-      server_name example.com;
-      listen 443 ssl http2 default_server;
-      listen [::]:443 ssl http2 default_server;
-      # Serve static files if found, otherwise proxy to Sanic
-      location / {
-        root /var/www;
-        try_files $uri @sanic;
-      }
-      location @sanic {
-        proxy_pass http://$server_name;
-        # Allow fast streaming HTTP/1.1 pipes (keep-alive, unbuffered)
-        proxy_http_version 1.1;
-        proxy_request_buffering off;
-        proxy_buffering off;
-        # Proxy forwarding (password configured in app.config.FORWARDED_SECRET)
-        proxy_set_header forwarded "$proxy_forwarded;secret=\"YOUR SECRET\"";
-        # Allow websockets
-        proxy_set_header connection "upgrade";
-        proxy_set_header upgrade $http_upgrade;
-      }
-    }
-
-To avoid cookie visibility issues and inconsistent addresses on search engines,
-it is a good idea to redirect all visitors to one true domain, always using
-HTTPS:
-
-::
-
-    # Redirect all HTTP to HTTPS with no-WWW
-    server {
-      listen 80 default_server;
-      listen [::]:80 default_server;
-      server_name ~^(?:www\.)?(.*)$;
-      return 301 https://$1$request_uri;
-    }
-
-    # Redirect WWW to no-WWW
-    server {
-      listen 443 ssl http2;
-      listen [::]:443 ssl http2;
-      server_name ~^www\.(.*)$;
-      return 301 $scheme://$1$request_uri;
-    }
-
-The above config sections may be placed in `/etc/nginx/sites-available/default`
-or in other site configs (be sure to symlink them to `sites-enabled` if you
-create new ones).
-
-Make sure that your SSL certificates are configured in the main config, or
-add the `ssl_certificate` and `ssl_certificate_key` directives to each
-`server` section that listens on SSL.
-
-Additionally, copy&paste all of this into `nginx/conf.d/forwarded.conf`:
-
-::
-
-    # RFC 7239 Forwarded header for Nginx proxy_pass
-
-    # Add within your server or location block:
-    #    proxy_set_header forwarded "$proxy_forwarded;secret=\"YOUR SECRET\"";
-
-    # Configure your upstream web server to identify this proxy by that password
-    # because otherwise anyone on the Internet could spoof these headers and fake
-    # their real IP address and other information to your service.
-
-
-    # Provide the full proxy chain in $proxy_forwarded
-    map $proxy_add_forwarded $proxy_forwarded {
-      default "$proxy_add_forwarded;by=\"_$hostname\";proto=$scheme;host=\"$http_host\";path=\"$request_uri\"";
-    }
-
-    # The following mappings are based on
-    # https://www.nginx.com/resources/wiki/start/topics/examples/forwarded/
-
-    map $remote_addr $proxy_forwarded_elem {
-      # IPv4 addresses can be sent as-is
-      ~^[0-9.]+$          "for=$remote_addr";
-
-      # IPv6 addresses need to be bracketed and quoted
-      ~^[0-9A-Fa-f:.]+$   "for=\"[$remote_addr]\"";
-
-      # Unix domain socket names cannot be represented in RFC 7239 syntax
-      default             "for=unknown";

-
-      # Otherwise, replace it
-      default "$proxy_forwarded_elem";
-    }
-
-For installs that don't use `conf.d` and `sites-available`, all of the above
-configs may also be placed inside the `http` section of the main `nginx.conf`.
-
-Reload Nginx config after changes:
-
-::
-
-    sudo nginx -s reload
-
-Now you should be able to connect your app on `https://example.com/`. Any 404
-errors and such will be handled by Sanic's error pages, and whenever a static
-file is present at a given path, it will be served by Nginx.
-
-
-SSL certificates
-~~~~~~~~~~~~~~~~
-
-If you haven't already configured valid certificates on your server, now is a
-good time to do so. Install `certbot` and `python3-certbot-nginx`, then run
-
-::
-
-    certbot --nginx -d example.com -d www.example.com
-
-`<https://www.nginx.com/blog/using-free-ssltls-certificates-from-lets-encrypt-with-nginx/>`_
-
-Running as a service
-~~~~~~~~~~~~~~~~~~~~
-
-This part is for Linux distributions based on `systemd`. Create a unit file
-`/etc/systemd/system/sanicexample.service`::
-
-    [Unit]
-    Description=Sanic Example
-
-    [Service]
-    User=nobody
-    WorkingDirectory=/srv/sanicexample
-    ExecStart=/usr/bin/env python3 sanicexample.py
-    Restart=always
-
-    [Install]
-    WantedBy=multi-user.target
-
-Then reload service files, start your service and enable it on boot::
-
-    sudo systemctl daemon-reload
-    sudo systemctl start sanicexample
-    sudo systemctl enable sanicexample
