Hi Victor, Socket handling for the TCP sockets is done by Twisted inside its TCP core, so you would have to look there to see what sort of options they set when opening a HTTP/WS connection handler. I personally have not seen too many issues with WebSocket timeouts, presumably as Daphne implements the WebSocket PING protocol to keep data flowing down the socket at regular intervals.
