Use aufs instead of ufs for better performance, and increase your cache size
for better caching (set to about a week's traffic).

Turn this off - you don't need it unless you are trying to debug a problem.

Anything other than ALL,1 should only be used when you are trying to
troubleshoot a specific problem.

The auth_param line is for Squid 2.5, and authenticate_program is for Squid
2.4. Remove the one that is wrong for your Squid version.

These acls are redundant - any one will work fine. Same for the
corresponding http_access rules.
