[Zope] Javascript won't refresh - Flush Cache??

I have a few pages of javascript laden dtml for getting syndicated headlines from moreover.com. The first time I opened the pages in Zope, everything was fine. Since then, I get only the headlines from that day (Dec 14) - is there a cache that can be flushed to get the most up to date headlines?? The original javascript works if it is opened directly in Netscape Navigator.
