[Zope] caching

I have a python function which returns a list of dictionaries (a result for an ldap query). But since I don't want to enrage the sysadmin or have a real slow page, I want to be able to cache this list in zope, and only update it every hour or so. The question then is : Could anyone suggest something to store this list in? Preferably something which could accept the the list as it is, and be able to return it in a way so that I could iterate over it and build my webpage. I'm really not sure what would be the quickest/and or easiest. all help would appreciated. Jorg Rødsjø
