About
The HTTP Upgrade request and response header can be used to upgrade an already-established client/ server connection to a different protocol (over the same transport protocol); for example it can be used by a client to upgrade a connection from HTTP/1.1 to HTTP/2, or an HTTP(S) connection to a WebSocket connection1.
