Hallo,
the Websocket protocol don't work. This will be used from a lot of client/server web application for server pushed messages.
here you find the wiki articel to this protocol:
WebSocket
WebSocket - Wikipedia, the free encyclopedia
spdy is a from google started protocol for a kind simular transfer, only that you can have more file transfers over one socket at the same time. The Websocketprotocol can only transfer 1 file at the same time, without the overhead from http. The initiation of the protocol is a http connection and then the server switch the client if he understand the protocol. this will be defined in the http header at the first connection.
kind regards
Alex
