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?

Any answers on this are appreciated.

Thank you.

At this moment (feb/2022) it seems that it's not supported. The recomendation is to use Application Gateway instead.

Yes, this is supported using the Azure SignalR managed service. The WebSocket connections will go to it instead of your backend pool.

  • Yes, this is what I was hoping for. I read somewhere that as long as Signal R services are used, it should work. We will give it a try. – Supreet Feb 24 '22 at 08:00
  • We have verified & can confirm that Azure Front Door does support the managed Signal R service provided by Azure. – Supreet Apr 22 '22 at 03:47
  • If we use Azure SignalR service, the client applications will build connections to Azure Signalr Endpoint or my external api (hub) endpoint ? – Ali Feb 14 '23 at 15:21
