From sgcWebSockets 4.4.8 the Log of websocket messages has been improved. Till now, the messages were saved as was sent/received by socket, this means that when a websocket message was sent by websocket client, this was first masked and then saved to log. As the message was masked, it can't be read easily so the log was useless for the websocket messages sent by client (the same for websocket messages received by server).
Teraz ramki websocket są domyślnie zapisywane bez maskowania (można to dostosować, korzystając z właściwości LogFile.UnMaskFrames). Gdy klient wysyła wiadomość, jest ona zapisywana bez maskowania; gdy serwer odbiera wiadomość websocket, jest ona również zapisywana bez maskowania (w przypadku serwera jest zapisywana zarówno zamaskowana, jak i odmaskowywana, ponieważ serwer może obsługiwać kilka protokołów i podczas odczytu bufora nie wie jeszcze, który protokół obowiązuje).
WebSocket Client Masked Messages
Przed tą zmianą wysyłane wiadomości websocket były zapisywane zamaskowane i tekstu nie można było odczytać.
