@miksago Thanks for the prompt reply. It worked and you're really awesome!

I didn't find a WebSocket Library that worked with the recent node.js, so that's why I started to write from the low-level. Anyway, seems your implementation would save my day.

Yeah, I've been working with ryan to add in certain things to node to make writing a websocket server more easy (like the upgrade event, great to see you using it there ;P )

As for my websocket-server library, I only develop to the latest HEAD builds, and in a few weeks time, I will hopefully have an early preview release of some extra stuff I'm adding to the server (channelling for instance) and also an implementation of draft76+, which includes a bunch of security updates to the protocol (means a lot more code)

The other thing with my websocket library is that it still works like a regular http.Server (apart from the first argument.), in order to listener for requests, you use the request event as used above. Also, the first argument to http.createServer should be optional.
