Sign in to saveWebSocket is a computer communications protocol, providing a bidirectional communication channel over a single Transmission Control Protocol (TCP) connection. The protocol was standardized by the IETF as in 2011. The current specification allowing web applications to use this protocol is known as WebSockets. It is a living standard maintained by the WHATWG and a successor to The WebSocket API from the W3C.

WebSocket is a computer communications protocol, providing a bidirectional communication channel over a single Transmission Control Protocol (TCP) connection. The protocol was standardized by the IETF as in 2011. The current specification allowing web applications to use this protocol is known as WebSockets. It is a living standard maintained by the WHATWG and a successor to The WebSocket API from the W3C.
WebSocket is distinct from HTTP used to serve most webpages. Although they are different, states that WebSocket "is designed to work over HTTP ports 443 and 80 as well as to support HTTP proxies and intermediaries", making the WebSocket protocol compatible with HTTP. To achieve compatibility, the WebSocket handshake uses the HTTP Upgrade header to change from the HTTP protocol to the WebSocket protocol.
