Yikes. 3.0.RC1 is at least better than the PRE versions, but it's still
not a Stable release. It's also nearly two years old. There have been

Yikes again. 777 permissions are not a good idea. Set the ownership
correctly, and put the directory permissions back to 750.

Old squid configurations contained an ACL defining anything with
"cgi-bin" or a question mark as a query and denying caching for matching
requests.
