The WebSocket protocol leverages the HTTP upgrade technology to upgrade an HTTP connection to a WebSocket. Once it is upgraded, the connection is capable of sending messages (data frames) in both directions, independent of each other (full duplex). No headers or cookies are required, which consi...
