[Zope] how to pass a variable stored in a REQUEST object from pages to pages

Hi all, How can I pass a variable stored in a REQUEST object to different pages WITHOUT using a form. Example: I have a page (.page template) called 'display' which receives information from a previous page. The information received is in . Request -> form -> afield On that 'display' page, I have several links to other pages, how can I transmit the same information (Request -> form -> afield) to the linked pages, so that they can use those values as well? Thanks in advance, -- Jean Baltus
