## Nginx HTTP server configuration for Spreed WebRTC

In general Nginx with websocket support is required (Nginx >= 1.3).

Add the following to your Nginx server section:

  location / {
    proxy_pass http://localhost:8090;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $connection_upgrade;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }

This is using a map to provide the Upgrade and Connection
headers to the backend server. You need to add this map to
the http section of your server:

  map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
  }

Also make sure that you have the general proxy configuration
like this in place:

  proxy_buffering             on;
  proxy_ignore_client_abort   off;
  proxy_redirect              off;
  proxy_connect_timeout       90;
  proxy_send_timeout          90;
  proxy_read_timeout          90;
  proxy_buffer_size           4k;
  proxy_buffers               4 32k;
  proxy_busy_buffers_size     64k;
  proxy_temp_file_write_size  64k;
  proxy_next_upstream error timeout invalid_header http_502 http_503 http_504;

And thats it.
