http-proxy doesn't proxy the latest websocket specifications

Created by: 3rd-Eden

Howdy,

A few days ago, we added FF6 and Chrome 14 websocket support to Socket.IO. But http-proxy doesn't seem to be able to proxy these upgrade events.

If I run a plain Socket.IO 0.8.2 chat example it works fine in FF6 and latest chrome, but if I add node-http-proxy infront of it only the Draft 76 specification receives a upgrade event.

After a bit digging I found out that https://github.com/nodejitsu/node-http-proxy/blob/master/lib/node-http-proxy.js#L862 doesn't get fired for the new websocket specifications (it does work for older websocket specifications like draft 76)
