Hi guys, is there a way to force a redirect to a login page when a session expires to prevent users from entering values in a page with an expired session?

He could  have just had all this in the layout page without calling the timeout variable from a controller function like this:

{{timeout = auth.settings.expiration}}

      <script>
     var timeout = {{=timeout}};
     var time = new Date().getTime();
     var refreshrate = 10000;
     $(document.body).bind("mousemove keypress", function(e) {
         time = new Date().getTime();
     });

     function refresh() {
         if(new Date().getTime() - time >= timeout*1000)  {
            window.location.href = "{{=URL('user',args=['logout'], vars=dict(_next=URL('index')))}}";
                }
         else {
             setTimeout(refresh, refreshrate);
                }
     }

     setTimeout(refresh, refreshrate);
     refresh();
</script>
