Mainly I'm interested in whether it's considered workable/usable.
    It doesn't seem to be working on my win 7 XAMPP PHP5.3 Local Server. 
The data still seems to exist if/when I "go back" to the preceding page 
of an e-mail form.

<?php
session_start();
header('Cache-Control: no-cache, no-store, must-revalidate'); //HTTP/1.1
header('Expires: Sun, 01 Jul 2005 00:00:00 GMT');
header('Pragma: no-cache'); //HTTP/1.0

TIA,

Twayne`
