RE: [PHP] Prefilled forms

Actually I am going back to the same URL. I am thinking it is an apache conf setting. See after I submit this email I can click back and will see the text that I am writing right now. If that form was coming from my server, it would be empty I am sure. Problem again: I have a form, fill it, click submit, then immidiately click back. Usually I see the data that I attempted to submit but on my server it shows a blank form.
