WebSocket Custom SubProtocols

Implemented from sgcWebSockets 4.1.4

Supported by:





WebSocket provides a simple subprotocol negotiation, basically adds a header with protocols name supported by request, this protocols are received and if receiver supports one of them, sends a response with subprotocol supported.

sgcWebSockets supports several SubProtocols: MQTT, WAMP... and more. You can implement your own subprotocols using a very easy method, just call RegisterProtocol and send SubProtocol Name as argument.

Example: you need to connect to a server which implements subprotocol "Test 1.0"

Client.Host := server host;

Client.Port := server.port;

Client.RegisterProtocol('Test 1.0');

Client.Active := True;
