How to forward request to Node.js from nginx with tcp_proxy_module?

Question

Now, I had patched nginx with the nginx_tcp_proxy_module, and it is running OK on port 8080.

How do I connect the clients to port 80 of nignx, not port 8080 of Node.js, so that having the nginx forward the request to Node.js?

Just change 8080 to 80. But TCP and HTTP on the same port is not possible.

Aleternative solution:

Use HAProxy on port 80
Set up nginx to listen on port 81
Run your node.js app on port 8080
Configure HAProxy to
- forward Host: your.nodejs.socketio.com to 127.0.0.1:8080
- forward everything else to 127.0.0.1:81

If you go down this route you will probably want to preserve client IPs:

Configure HAproxy
Use RealIP module in nginx

Use X-Forwarded-For in socket.io

socketio.handshakeData = function(data) {
    var d = socketio.Manager.prototype.handshakeData(data);
    d.ip = data.request.headers['x-forwarded-for'] || data.request.connection.remoteAddress;
    return d;
};

Thanks, now haproxy had successfully forwarded http request to nginx and websocket requests to nodejs(only in chrome), but fail to forward xhr-polling and jsonp-polling requests( ie and firefox)
