NGINX to reverse proxy websockets AND enable SSL (wss://)?

Just to note that nginx has now support for Websockets on the release 1.3.13. Example of use:

location /websocket/ {

    proxy_pass ​http://backend_host;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_read_timeout 86400;

}

You can also check the nginx changelog and the WebSocket proxying documentation.
