Session state modes in ASP.NET

The different session state storage options, Asp.net Supports are:

1. In-Process(default). It stores session state locally on same web server memory where the application is running.
2. In StateServer mode, each session is converted to XML (serialized) and stored in memory in a separate process (aspnet_state.exe). This state Server can run on another machine.
3. SQLServer mode stores session state in SQL Server database. It has the same advantages as that of StateServer.
4. Custom modes allows to define our custom storage provider.
5. Off mode disables session storage.
