This is what our websocket handhakes are looking like when they come from a particular client that is behind a Blue Coat proxy

Hey did you ever figure out how to deal with this?

Seems like those orwellian fucks at Blue Coat don't support websockets at all, so even if you did do the handshake with that request, you'd just end up with opcode -1 no matter what.

Seems like web sockets are supported in newish versions of Blue Coat Proxy SG: http://bluecoat.force.com/knowledgebase/articles/Solution/WebSocketsupportintroducedinSGOS6552PR
