I would like to get details on the behavior of the app with ARR Affinity enabled and autoscaling.
Let's say I deploy a stateful ASP.NET web app on Azure Web App. Therefore I enable ARR Affinity. I configure autoscaling as well.
What happens if ever an instance is put down due to autoscaling. Does ARR Affinity prevent the scale in as long as user session is still active, or is the user session suddenly broken?
Could you please then give pieces of advice on how to configure stateful application in Azure Web App (or something else)?
