title: Session Time Updation for New Tab Opening
body: <p>I have level 1 &amp; level 2 menus in my application.</p>
  
  <p>In session_start() method, I wrote code to add "session start time" in session variable.</p>
  
  <p>Now when I open new tab for one of the Menus (from Level 1 or Level 2) I want to update the session start time.</p>
  
  <p>Is it possible to do it ?</p>
  
  <p>Currently I am using javascript &amp; cookie mechanism for it. I want to handle this from server side. </p>
