So you had a form on the first page. When the user entered some data she gets a second page without a form and you want to passthe data on to a third form? Your problem is that there is no form on the second page so that you thought of usingcookies to keep the data, right?
You could avoid cookies if you use a hidden form on your second page with just a submit button visible. All the data the user entered would go into a collection of
<input type="hidden" name="name" value="usersvalue">
But that's not a perlish answer ;-)
