title: Preventing users from performing actions which are more than 15 minutes apart
body: <p>I want to prevent users from performing actions which are more than 15 minutes apart, but I don't really need the <code>Session</code> object for saving any data. </p>
  
  <p>Is setting <code>SessionState</code> <code>timeout</code> to 15 minutes enough, although I don't user the <code>Session</code> object in my code?  </p>
  
  <p>Is there a way to do that just through configuration, without code, or Should I put a dummy object in the Session and then rely on the timeout?</p>
