C # Asp.net IIS set the session expiration time in Web. config and IIS

Sometimes in the web. config sets the sessionstate or sets the session in the class file. timeout: During access to IIS, it times out every time it fails to reach the time. The reason is that the session timeout is set in IIS, and the session method in IIS is:
In IIS, right-click the default website-> main directory-> ApplicationProgramSet the point in configuration-> options-> enable session Status-> set the time for Session Timeout

Set the session expiration time in Web. config:

<System. Web>

<Sessionstate mode ="Inproc"Timeout ="60"/>

</System. Web>

Settings in the aspx file:

Session. Timeout = 60;
