Custom Websocket-Header

[mafe]

I am using this library as a client, in order to connect to a ashx-WebSocketHandler in asp.net, but it is not possible to connect to it with the default protocol header that is in the library.

With the following header it works:

    "GET /WSHandler.ashx HTTP/1.1\r\n"
    "Host: " + _host + ":" + _port + "\r\n"
    "Connection: Upgrade\r\n"
    "Pragma: no-cache\r\n"
    "Cache-Control: no-cache\r\n"
    "Upgrade: websocket\r\n"
    "Origin: ws://websocketorigin\r\n"
    "Sec-WebSocket-Version: 13\r\n"
    "Sec-WebSocket-Key: " + client->cKey + "\r\n";
    "Sec-WebSocket-Protocol: chat\r\n"
    "\r\n";

Is or will it be possible, to configure it from the main sketch in future?

most likely the protocol is not set correct.

you can try:

   webSocket.begin("192.168.0.123", 81, "/WSHandler.ashx", "chat");
