Hi Cosmo, > acl localnet proxy_auth REQUIRED src > xxx.xxx.xxx.xxx/16 > acl proxy_a_users external win_domain_group > group_proxy_a acl proxy_a_sites dstdom_regex [-i] > "c:/squid/lists/proxy_a_sites.txt" > acl proxy_b_users external win_domain_group > group_proxy_b acl proxy_b_sites dstdom_regex [-i] > "c:/squid/lists/proxy_b_sites.txt" Do you really have the square brackets around the "-i"? I don't expect that to work. And the format looks confusing, too. Could you post your lines without line breaks, please? Or at least make clear what belongs to one line.
