I like to get user selection from the browser via checkboxes. The problem is that I have 1000s of item and I can display only 20 at a time. So after user selects the item, I like to present next screen to select other items. When user is done selecting all items, I like to process those items. My item ID are 32 digits long. What methods I use to retain selections of user across different screen. I am running apache, but not mod_perl.
