title: ASP.NET: Maintain variable value after session expires
body: <p>I'm developing a website in which the session must expire in 15 minutes.  After 15 minutes, the user's redirected to another page once they click any buttons.  My problem however, is after the session expires, there's one value in an integer variable I need to maintain.  </p>
  
  <p>What's the best way to keep this value after session expiration?</p>
  
  <p>Thanks</p>
