Hi all I have installed avgfree antivirus in the clients of my net, and i have configured them to update their signatures using my squid proxy (2.5Stable3) They are working fine but the problem is that the update files (.bin) are not being cached. This is a part of the access.log. 1106765778.379 27278 10.21.6.169 TCP_MISS/200 949270 GET http://free.grisoft.cz/softw/70free/update/u7avi439u39282.bin - DIRECT/193.86.3.37 application/octet-stream I have put this lines in the squid.conf refresh_pattern -i \.bin$ 240 90% 1440 override-expire override-lastmod ignore-reload refresh_pattern -i free.grisoft.cz 240 90% 1440 override-expire override-lastmod ignore-reload but inspite of this, i cant get a HIT. How can i make this files cacheables ? Thanks. Diego
