What is the use of stateConnectionString in sessionState in Web.config?

I'm using VS 2005 for web forms.

Looking at the web.config I see a stateConnectionString attribute.

• Is this really needed?
• 开发者_StackOverflow中文版When is this needed?
• How is this used?

Do you mean sqlConnectionString attribute? If you do then it is used if you set the state server mode to SqlServer for usage in a web farm scenario. It is the box running the Sql Server for the session state store.
