Roman vs Caches

I'm struggling with caches now;

1. Flock doesn't seem to pick up feed-changes (which with other readers work) - even if I force it to reload
2. Google Desktop seems to cache XmlHttpRequest results, without me being able to control it (setting headers like pragma, cache-control, etc)

Good thing I finally found my snoop equivalent for windows: Ethereal. So at least I have some aid for debugging...
