In the incoming handshake message authenticate an user, in the ext var he send me a key, password. i can verify that, OK!. the problem is how to respond with a generated auth_token in the outgoing handshake. But in that case i dont have any idea to know who is that person, is the same that i authenticate, i don't think so. i want to use that handshake to authenticate user and respond an auth tomen to consume the subscribe and send message faye events.
