Windows.Networking.Sockets.IWebSocketInformation.Protocol

-description

Gets the WebSocket sub-protocol negotiated with the server during WebSocket handshake on a IWebSocket object.

-property-value

The sub-protocol negotiated with the server during WebSocket handshake.

-remarks

Both a WebSocket client and a WebSocket server may support multiple sub-protocols. During the WebSocket handshake, the server will select one of the sub-protocols from the mutually supported sub-protocols and reply in the "Sec-WebSocket-Protocol" header. The Protocol property will contain the selected sub-protocol string.

Before the IWebSocket is connected, this property is null.
