Introduction to WebSockets

WebSockets is a bi-directional, full-duplex, persistent connection from a web browser to a server. Once a WebSocket connection is established the connection stays open until the client or server decides to close this connection. With this open connection, the client or server can send a message at any given time to the other. This makes web programming entirely event driven, not (just) user initiated. It is stateful. As well, at this time, a single running server application is aware of all connections, allowing you to communicate with any number of open connections at any given time.
