title: Azure Front Door with Azure Signal R
body: <p>Does anyone has any experience with Azure front door used with an app service that uses azure signal r service (managed azure signal r service)
  Based on my reading so far I understand that AFD doesn’t support web sockets, which looks like if you are using signal r within your app then probably that’s not yet supported. In our case we are using signal r Azure service which is external to our app service, is this supported with Azure front door?</p>
  <p>Any answers on this are appreciated.</p>
  <p>Thank you.</p>
