Redirecting websocket traffic on port 80 with lighttpd

I have a website hosted on lighttpd, accessible at the "www" subdomain. I also have a chat server listening on port 8124 made with node.js and socket.io. I want all client traffic to happen on port 80, by redirecting all requests to the "chat" subdomain to port 8124. So I enabled mod_proxy and in lighttpd.conf I added: ``` $HTTP["host"] == "chat.myserver.com" { proxy.server = ( "" => (( "host" => "78.128.79.192", "port" => "8124" )) ) } ``` On the client, when I connect to the websocket, ``` var socket = io.connect('http://chat.myserver.com'); ``` I get the right messages from node.js: ``` debug - client authorized info - handshake authorized 6067470561567883577 debug - setting request GET /socket.io/1/websocket/6067470561567883577 debug - set heartbeat interval for client 6067470561567883577 debug - client authorized for debug - websocket writing 1:: ``` But the browser gives an error: ``` Firefox can't connect to server ws://chat.myserver.com/socket.io/1/websocket/6067470561567883577 ``` Of course, everything works correctly if I connect directly to the port 8124: ``` var socket = io.connect('http://www.myserver.com:8124'); ``` But, as I said, I would like all client traffic to be on port 80. Is it possibile?
