I did this using PHP and Javascript not too long ago. My solution may
not be elegant but it works.
I set up an inline frame on a page that had my large form. I set the
soruce of the frame to my processing page and set the display style of
the frame to none using CSS. Then for all the form elements, I set an
onchange event that called a javascript function. The function creates
a query string that is passed to the source page of the frame.
