Doc from org.springframework.web.socket.sockjs.transport.TransportHandler.checkSessionType.

Check whether the type of the given session matches the transport type of this TransportHandler where session id and the transport type are extracted from the SockJS URL.

Returns:boolean

true if the session matches (and would therefore get accepted by handleRequest), or false otherwise
