ttl_pattern or refresh_pattern?

refresh_patterns are done on a first-match basis, so your problem is
simply solved by:

refresh_pattern/i \.(jpg|gif)$ 5 200% 10080
refresh_pattern/i \.(mov|avi)$ 5 300% 15120
refresh_pattern/i www\.cnn\.com 5 20% 360

to others on this mlist, how abt swapping refresh_patterns on your
site? who has done clever tricks, like the above for cnn.com?
