The website we are building relies heavily on 'parameters' that are set throughout the site. A value entered in the first form on page 1 must be persisted and retrievable from page 10, or any page for that matter. I have approximately 50 parameters I will have to keep for the life of a user's search. I DO NOT want to use the session to store the parameters in because this will cause problems if a certain course of action is taken. Is it possible for me to carry the REQUEST object from one page to another, while adding, changing, or even deleting some of the values it contains, for the life of a search? This REQUEST object will have to travel in and out of Python scripts, DTML Documents and Methods, and other objects. At certain times, I will want to retrieve one or more of the parameters to use the value or change it. When changed, I will need to place the new value in the REQUEST object. If I don't need a certain parameter in a certain place, I do not want to have to mess with it at all, and still have it remain in the REQUEST object and continue to be avaiable to the next page if necessary. Please understand I am very new to Zope. My company is trying to transition from Java and JSP to Zope and Python. I need to make sure I can handle this situation elegantly before proceeding. Any suggestions will be greatly appreciated. Stacy
