refresh page (might be 0t)

Hey, Have run into a little problem...any help appreciated. Heres what I am doing: I give the client a control panel where he can add,edit and delete accounts, after each of the actions I have a link back to the index page of the contol panel...problem is, unless he presses the refresh button it shows him the same cached content. How do i force the browser to display the new updated accounts after and edit or the new list of accounts after a delete? I KNOW php is server side and this is a browser issue...but maybe this can be done with headers or something? Thanks, -Ryan
