In the script to which the form submits, store the $_POST data somewhere
else, say a session. Then, use this:

header("Location: http://host/path/to/script.php");
exit();

to bounce the user to another page. Most browsers know to not re-submit the
post data to this new page. The new script can even be the originating
one - as long as you use the location: header, you'll be fine. You can then
access the submitted data wherever you stored it.

PS. if you're using a session to store the data, call session_write_close()
before the header() call, otherwise nasty things happen on some browsers.
