acl control before dns lookup

Hi all,
        in my squid.conf i setupped some acl to prevent sex sites, download
and other good thigs like stop of some banner sites.Everything works well
but i see that the acl is readed after a dns lookup of the host.In poor word
if i have www.playboy.com in the list of denied sites and someone write it
on the browser, the link goes up for a request to the dns and then squid
show the denied messages.IS it possible to make it reverse?? i means is it
possible to tell squid to see if the request is allowed and if yes then go
on to find the site???

                                thanks
