Squid acl rules can be configured to allow specific ip's to get full access, or rather skips the blocked site list.
acl <tag> src x.x.x.x # ip address for full access workstation
acl blocksites url_regex "/root/BlockedSites.file"

http_access allow <tag>
http_access deny blocksites
http_access allow all

From all the ways i tried, squid does not log urls accessed by the allowed ip's.
Is there a way to have squid log the urls requested from allowed ip's?
