[squid-users] http_access allow ...

I'd like Squid to be configured to allow all traffic except for a list
of ad servers, but it doesn't seem to be working...
I have the following line in Squid:

acl ads dstdom_regex -i "/etc/squid/adservers"
http_access deny ads

The adservers file then contains regex expressions for various ad servers, etc.

This Squid process is only listening on localhost as it gets the
request from DansGuardian in front of it.

Here's my acl lines:

acl QUERY urlpath_regex cgi-bin \?
acl QUERY urlpath_regex download
acl QUERY urlpath_regex exe
acl QUERY urlpath_regex zip
acl QUERY urlpath_regex 160
acl ads dstdom_regex -i "/etc/squid/adservers"
acl all src 0.0.0.0/0.0.0.0
acl manager proto cache_object
acl localhost src 127.0.0.1/255.255.255.255
acl to_localhost dst 127.0.0.0/8
acl SSL_ports port 443 563
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 563 # https, snews
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT
acl PURGE method PURGE

And here's my http_access lines:

http_access deny ads
http_access allow PURGE localhost
http_access allow all
http_access allow manager localhost
http_access deny manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost

Any ideas what I'm missing?
Thanks,
~M
