No handling of connections suspended by a proxy

[Incognito]

Sometimes a proxy server that doesn't mange websockets correctly will be used (sometimes on the client's network somewhere also), and when this happens the request can be forever in a state of pending, saying the "connection is established" on my server but the client will never reach the onOpen callback.

This is kind of tricky because there's no clear way to test for it.

One such proxy that has this behavior is pound: http://www.apsis.ch/pound/

To be more clear here's what happens step-by-step:

1. Client requests upgrade connection via ab
2. Request is passed through proxy to WebSocketServer
3. Upgrade response is sent back to proxy
4. Proxy suspends all socket traffic because it can't deal with it.
5. connection.onOpen is never called while pending

AutobahnJS can't to anything about broken proxies. Establishing the WebSocket connection is browser business. You might try to use TLS (secure WebSocket aka WSS) to prohibit proxy inteference (this will work unless you have a MITM proxy).
