Will “Always On” setting prevent BOTH idleTimeout and periodicRestart?

Question

Has you may know, Web sites hosted under Microsoft Azure Web Sites service are by default configure to timeout after idling 20 minutes (idleTimeout) and the application pool

Answer 1

Yes both of them will be prevented.

The default 29 hours periodicRestart was never on Azure Websites. That feature is an IIS feature that was enforced by WAS and was designed to run on a server level meaning restart all the worker processes on an IIS server. Both these things (WAS and IIS Server) don't apply to Azure Websites as WAS was the process management component of IIS and that was very specific to one box setup. Azure Websites uses a different process management component that doesn't have periodicRestart.
