Do I need SessionStateModule in my ASP.NET MVC3 application hosted in Azure web role?

Question

In my ASP.NET MVC3 application I don't ever explicitly use SessionStateModule and so I assume I can just remove it by changing web.config . The application is hosted in Azure web role so I can't rely on per-instance session states anyway, can I?

Will removing this module likely break something or can I just remove it?

Answer 1

You are right, InProc will not work on Windows Azure. Here some options:

-Store session state using Sql Database

-Store session state using Table storage

-Store session state using Windows Azure Caching (recommended)

Answer 2

It depends on how your application is designed and what features you are using. If the application is 100% stateless, then session state can be removed.
