title: InProc session timeout not working
body: <p>I'm using asp .NET MVC app, and I've configured</p>
  
  <pre><code>&lt;system.web&gt;&lt;sessionState mode="InProc" timeout="90" /&gt;&lt;/system.web&gt;
  </code></pre>
  
  <p>but It looks like session still valid only 20 minutes instead of 90, why?</p>
  
  <p>How can I make this effective instead of the 20 (default I suppose)</p>
  
  <p>I've checked te idle time in the application pool, it was 20, is that the cause of the timout? If yes, how can I override this from config file?</p>
