[squid-users] TCP_DENIED/403 errors when ads blocking is activated

[Nicolas]

You're right, Matus. That was the issue.
I replace as you suggested:
acl ads dstdom_regex "/etc/squid/ad_block.txt"
by
acl ads dstdomain "/etc/squid/ad_block.txt"
and now it works.

Thank you very much, Matus !

Have a nice day.

Nicolas.
