[Zope] Question about URL lookups

Sorry if this is too generic a question but thought I would throw it out. Interested in doing a page that does a ZSQL lookup based URL parts but not like a normal db lookup. I want another way to do: domain.com/LocalSearchFolder/lookup?category=27&state=va&city=Fredericksburg More like this: domain.com/LocalSearchFolder/L-Fredericksburg/S-VA/C-Plumbing And that page (ummmm...DTML preferably) would display the lookup results for Plumbing contractors in Fredericksburg, VA. Any pointers to ideas?? Thanks! -Allen
