title: Unlimited session timeout in asp.net
body: <p>I need to keep the session of my application alive.  I have seen that it can be set to a certain time by implementing the following code:</p>
  
  <pre><code>Sub Session_OnStart
      Session.Timeout = 90
  End Sub
  </code></pre>
  
  <p>Is there any way to make in unlimited?
  Thanks</p>
