Re: Form data is not "remembered"

If the form page is not being cached, it would probably get reloaded when they clicked back, thus losing the data. I'd suggest redrawing the form with the fields populated and with the appropriate error messages. Then you don't need to mess with caches or sessions for that matter, and the user doesn't need to take an extra step to get back to the form.
