Unless you do something rather obtuse like using Javascript to
serialize multiple HTML forms into separate JSON objects and then
combine those into a single JSON object and then submit that via an
AJAX call.  [You could use XML instead of JSON, but that'd be even
worse.]

I've no clue _why_ somebody would go to the trouble to do something
like that -- if you know how to stuff like that, then you probably
know better than to actually do it. ;)

If the data on some set of multiple forms is always going to be
submitted together, then just use a single form instead.

If you want to handle multiple different forms _one_at_a_time_ using a
single form handler, then just put a hidden input field on each form
that identifies which one it is.
