Some options I've used previously, some kinda yucky I admit. 1) Use the GET method. You can send data this way as long as the url isn't very long. Don't forget to urlencode() if required. 2) Add a 0 second meta refresh on the POST'd-to page. If the user hits back they will go to your intermittent page just after the form, not the form page itself. 3) Use a header() call to send the user to a totally new page after the POST. -- Greg Donald
