If the server agrees to the change, the connection becomes a transparent data link between client & server, without the usual restrictions on HTTP content. WebSocket proxying. To turn a connection between a client and server from HTTP/1.1 into WebSocket, the protocol switch mechanism available in HTTP/1.1 is used..
