What kind of information do you want to pass? Is it possible
to express this as selection fields on the initial form?

If you use a script at the server to generate the form for
a particular database, you can then tailor the form according
to info entered in the initial form.

The latest ideas for forms include a new STATE element that
allows servers to store information in forms in a manner
that is opaque to browsers. Other changes on the way will
allow forms to be dynamically updated when a user makes
a selection without the need to resend the entire form.

These ideas will be discussed in the May WWW conference.
