In this post, I will demonstrate how to use Azure Redis Cache for storing ASP.NET session state. In Azure, In-Proc session mode does not work as our application will be working with sticky sessions on a load balancing scenario. In this context, ASP.NET session state and caching do not work so that we have to put ASP.NET state information on a persistent storage. And it is very important that we should develop the cloud apps in stateless manner so that we can easily scale our apps. In Azure, we can leverage the following storage options as a persistent storage for storing ASP.NET state information.
