The WebSocket protocol was standardized by the IETF as RFC 6455 in 2011, and the WebSocket API in Web IDL is being standardized by the W3C. WebSockets defines a protocol and a simple way to send data, but an extension such as compression could allow sending the same data but in a shorter format. Extensions are explained in sections 5.8, 9, 11.3.2, and 11.4 of the spec. Making a WebSocket connection, sending and receiving data, and closing the connection.
