[Zope-dev] Passing variable across pages

Hi All, I have a query page which gives multiple category results. I would like to list the categories in a intermediate page and link them to multiple pages. I have a single script which generates multiple category outputs. I would like to pass the variables for each of the categories pages through the intermediate page. I tried by storing them in session variables. but the sessions get expired quickly. I tried passing them through query string, but the results are with multiple lines(say 40,000) Please suggest me a solution for this. Thanks and Regards, Babylakshmi
