Dec 29, 2015 · To work around the “WebSocket is dead but still appears open problem” WebSocket implementers usually introduce a ping/pong message. This solution works fine provided you are running over HTTPS, but over HTTP all bets are off and rogue proxies will break you.

So a simple way to build is to open websocket-sharp.sln and run build for websocket-sharp project with any of the build configurations (e.g.

The server does not send pings. Note: QWebSocket and QWebSocketServer handles ping requests internally, which means they automatically send back a pong response to the peer. See also pong().

The standard also supports ping/pong (heartbeat) frames that allow either the client to verify the status of the connection. Feb 19, 2014 · When debugging the websocket server code, it looks like there is a WebSocket PONG event being sent to the server (with a few bytes of data), which we do not reply to (and that sequence repeats a few times) and then the client sends the close packet, we send a close response (and the connection is closed). a “ping” packet is sent by the client in a WebSocket frame, encoded as 2probe by the engine.io-parser, with 2 being the “ping” message type..
