Make SQUID log urls for allowed ip addresses

Hi,

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?

Specs:
squid ver : (squid/2.6.STABLE21)
OS : CentOS 5.5

Thanks.
