Describe the bug

Azure SignalR SDK returns 200 for SignalR path requests[ reconnect, poll... requests with valid token].
It should fail because those requests should be handled by SignalR service.

To Reproduce

  1. Use a AspNet SignalR Client to connect to a self-hosted SignalR server, setting the protocol to long-polling
  2. Stop the self-hosted SignalR server. Then the client would try reconnecting.
  3. Start the Azure SignalR app server (same host and port). Then the reconnect will succeed and the client would keep sending /signalr/poll to the server.
    poll

Further technical details

Azure SignalR SDK version <=1.7.1
