What What is is session session state state? ? Session state is usually used to store and retrieve values for a user across ASP.NET pages in a web application. There are four available modes to store session values in ASP.NET: In-Proc, which stores session state in the individual web server s memory. This is the default option if a particular mode is not explicitly specified. State Server, which stores session state in another process, called ASP.NET state service. SQL Server, which stores session state in a SQL Server database Custom, which lets you choose a custom storage provider.
In In- -Proc Proc session mode does not work in session mode does not work in Windows Windows Azure Azure
