How to use ASP.NET Session State Server

StateServer mode stores session state in a process, referred to as the ASP.NET state service, that is separate from the ASP.NET worker process or IIS application pool. Using this mode ensures that session state is preserved if the Web application is restarted and also makes session state available to multiple Web servers in a Web farm.

The following example shows a configuration setting for StateServer mode where session state is stored on local:

<configuration>   <system.web>     <sessionState mode="StateServer"       stateConnectionString="tcpip=127.0.0.1:42424"       cookieless="false"       timeout="20"/>   </system.web> </configuration>
