2. Redirect browser location using servlets!

When the session expires, I want the user to be send to login screen again. But, if I use sendRedirect(target) from a frame in a browser, only that particular frame redirects to login screen. How can I make the parent(browser) location move to the login screen by calling sendRedirect(target) from one of the frames? Thanks! -Sam
