What are the different types of Session state management options available with ASP.NET?

In-Process state management:

• The In-Process type of Session state management stores the session in memory on the web server.
• In order to have a user always reconnect to the same web-server, a sticky server is needed.

Out-of-Process state management:

• Out-of-Process Session state management stores data in an external data source.
• The external data source may be a SQL Server or a State Server service.
• Out-of-Process state management requires the objects in a session to be serializable..
