Websocket is a promising technology for more advanced web applications. Websocket allows to make a continuous two-way connection between the application software running on web browser the software running on server. WebSocket represents the next evolutionary step in web communication compared to Comet and Ajax. The WebSocket standard (when it gets ready and widely supported) promises to simplify much of the complexity around bi-directional web communication and connection management. After a complex handshake confirming both sides really speak websocket, websocket protocol is MUCH simpler than HTTP.
WebSocket network technology has just taken two important steps toward standardization:
IETF Standard Organization has published RFC 6455 The WebSocket Protocol document. This is a draft standard, which is considered stable.
