[Zope] REQUEST is too crowded

I'm refering to a ZCatalog using a variable zcatalog which contains the name of the Zcatalog: <dtml-in "_.getitem(zcatalog, 1)"> <dtml-call "REQUEST.set('newurl', '/' + getpath(data_record_id_))"> </dtml-in> So I need to pass the search parameters via REQUEST. Unfortanutely, REQUEST already has all kinds of variables set in it because this is a rather involved procedure, and these variables may affect the search results. I need to pass the search terms to the Zcatalog somehow, or make a empty REQUEST variable - any ideas how? I can only call the Zcatalog using _.geitem or the like. -- Itamar - itamars@ibm.net
