Amos,

I've implemented the example you sent on Dynamic Content but so far i
regret to say that no improvement has been made on the hit ratio

I added the following to my squid.conf

refresh_pattern (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320
acl mydomain dstdomain .mydomain.com
cache allow mydomain

my stats look something like this:

67.5103% TCP_MISS/200
6.07349% TCP_HIT/200
4.55681% TCP_MEM_HIT/200
1.59761% TCP_IMS_HIT/304

Any help is appreciated.

Thanks
