The default ping handler sends a pong to the peer. The application's reading goroutine can block for a short time while the handler writes the pong data to the connection. The application must read the connection to process ping, pong and close messages sent from the peer. The websocket connection lifespan and frame structure.¶ Websockets have four states: connecting, open, closing and closed.

The Sec-WebSocket-Accept header is important in that the server must derive it from the Sec-WebSocket-Key that the client sent to it. To get it, c oncatenate the client's Sec-WebSocket-Key and the string "258EAFA5-E914-47DA-95CA-C5AB0DC85B11" together (it's a "magic string "), take the SHA-1 hash of the result, and return the base64 encoding of that hash.

To avoid connection timeouts and prevent proxies from closing connections, WebSockets can send ‘ping/pong’ requests. The server periodically sends a 'ping' control frame and the client responds with a 'pong' control frame. The ping/pong approach resolves two problems: It makes sure the second party is still functioning

Note that when a ping message is received, a pong is instantly send back as requested by the WebSocket spec. Note that a control frame's payload length must be 125 bytes or less (RFC 6455, 5.5. Control Frames).
