[Pan-users] How to Clear the Cache

[Michael]

I have several high-traffic groups that I watch. All of them have over 
500,000 headers saved. Every time I load these groups, it takes forever 
to load all of the headers, score them, then download new headers, and 
score the new headers. Is there any way of purging the old headers 
after a certain date or time? I don't like wasting so much time waiting 
for all of these old headers to be loaded and scored.

Thanks,
Michael
