title: Portlets - Keeping session alive from server side
body: <p>I am implementing jsr 186 portlets, with some servlets to the mix to implement some ajax. The problem is if I only make AJAX calls for some time, I lose the session. Strangely, keeping alive the servlet session does not prevent the portlet session from timing out.</p>
  
  <p>Is there a way I can keep the session alive from within my servlets, on the server side?</p>
  
  <p>FWIW I'm using spring and spring mvc/portlet.</p>
  
  <p>Thanks,
  Miguel Ping</p>
