+Application Gateway provides native support for the WebSocket and HTTP/2 protocols. There's no user-configurable setting to selectively enable or disable WebSocket support.
 
 The WebSocket and HTTP/2 protocols enable full duplex communication between a server and a client over a long running TCP connection. This allows for a more interactive communication between the web server and the client, which can be bidirectional without the need for polling as required in HTTP-based implementations. These protocols have low overhead, unlike HTTP, and can reuse the same TCP connection for multiple request/responses resulting in a more efficient utilization of resources. These protocols are designed to work over traditional HTTP ports of 80 and 443.
