Socket.io and nginx workaround

socket_client.html

<!-- include that socket client that socket.io serves out -->
<script src="//yourdomain.com:8080/socket.io/socket.io.js"></script>
<script type="text/javascript">
    //connect your client to the socket server.  Make sure that you specify
    //the port here.  It needs to be the same as what nodejs is listening on
    var chat = io.connect("yourdomain.com:8080");
    
    //add all your chat.on custom events next
</script>

socket_server.js

/* most reverse proxies struggle working with websockets
*  Many fixes require additional modules or tweaks to
*  the proxy (nginx, HAproxy, etc)
*  this is a pure javascript solution to get it working
*
*  The ideal workflow is this:
*
*  nginx listens on port 80
*  nodejs listens on port 8080
*  socket.io listens on port 8080 through nodejs app
*  nginx proxies any requests on port 80 over to nodejs on 8080
*  socket.io client connects directly to node/socket server on port 8080 
*  and communicates directly without involvement of a reverse proxy

//create the node server, have socket.io listen on it
var app = express.createServer() 
  , io = socketio.listen(app);

//have node listen on a port other than 80
app.listen(8080);

//set up socket,io to do whatever you want
io.configure(function(){
    io.set("authorization", function(handshakeData, accept){
        //authorization code here
    });

    //accept connection from anywhere, this is default
    io.set("origins","*:*");
});

//socket connection
io.on('connection', function (socket) {
    //add all of your socket.on custom events here
});
