[Zope] Script caching

Hello, I need to cache the results from a parameterized python script that makes a parameterized database call for a long period of time (about a day) as the data doesn't change much. I have associated the script w/ a ram_cache manager and cranked up the expiration time but don't to be getting the consistent behavior I was expecting. The documentation in general for the zope caching seems pretty impoverished. Anyone know how to do this? Thanks, C>T>
