Web Sockets are not standard HTTP connections. The "handshake" is HTTP,
but after the handshake, the protocol is message-based. Consequently,
most of the Tornado HTTP facilities are not available in handlers of this
- type. The only communication methods available to you are send_message()
+ type. The only communication methods available to you are write_message()
and close(). Likewise, your request handler class should
implement open() method rather than get() or post().
