I'll agree with the last poster on using hidden fields. They are a quick and easy way of allowing you to save state if you have dynamically served all of the pages. Otherwise you have cookies (properly used of course) to save state. I'm pretty sure that is what CGI does to maintain which browser's state to recall in that file. Note that this could possibly screw up something if the user is clicking the forward and backward button's a lot. This would cause the state in the file to be out of sync with actual page displayed. Hidden fields do not have this problem. (state is cached in the page)
