This prob doesn't work, but you can get the idea:

refresh_pattern/i ^http://.*microsoft\.com/.*\.jpg 86400 50% 432000
refresh_pattern/i ^http://.*microsoft\.com/.*\.html 7200 50% 432000
refresh_pattern/i ^http://.*microsoft\.com/.* 3600 90% 172800

You get the idea.. You might also want to make it cache thing on
that look like cgis.. As they use things like that for alot of regular
content.. Also look out for espn..

 Also, we should make clients requesting Pragma: Nocache, IMS-Get but not
through the hierarchy.. (Or if we have to go through the hierarchy, then
we Pragma: Nocache)..
