Optional subprotocols supported by the client.
property SubProtocols: String read get_SubProtocols write set_SubProtocols;
This property is optional. Set this property to one or more comma separated subprotocols the client supports. These should be provided in order of preference. For instance: "chat, superchat".
The server will accept one subprotocol during the connection. After the connection is established this property will be updated by the component to reflect the value the server chose. Query this property to determine the negotiated subprotocol.
This property is not available at design time.
