[Zope] Cookies

Hi! I'm trying to use cookies via DTML. I need to get information from a cookie and send it to a Query. I find searching on the Zope site frustrating and cannot find any examples on how to GET information from a cookie. Basically, what I am trying to do is push the 'where' statement from one page to another, then to the query. First, is a cookie the best thing to use here? Second, should I use the request object to set the cookie, or can I do it the javascript way. If I need to use DTML, how do I do it? Third, how do I retrieve the information? Thanks in advance, -y ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Yvonne Totty
