RESPONSE.set is an ancient artifact that is merely exposing the out of
date nature of the ZQR. At any rate the problem you are running up
against is the stateless nature of HTML. There are several ways to
accomplish your goal:

1. Pass the values again by populating hidden fields on a form and
submitting the form.
2. Pass the values by explicitly rewriting URLs with the variable/values
you want.
2. Store the values in a Cookie.
3. Use a session management tool. There are several available for Zope.
