I have a Parent Page where ExtJs is placed.
On click of links in the left panel, I am loading the pages in tabs through IFrames.
Now, If the session expired, when I click on any link in the left panel,
the tab opens and Login page is displayed within the TAB. But the Parent Page is not getting refreshed.

So, what I want is when any link on the left panel in parent page is clicked, it should check for the session expiry and redirect to login page.

Is this possible to handle in ExtJs??
