Hi,
Actually, the reason why form data is not remembered is because I use
sessions, and when you use sessions, the browser is told not to cache
anything, which is pretty smart actually.
The easy solution is to store the user's input into a session variable to
"remember" it that way, and display the form again in case of an error with
the saved values restored into the form.
This is particularly easy if you have an object that you want to define
using your form; you can easily save the whole object as a session variable.
