I changed Squid 'denied' error pages (added random-colored background).
Now all ads IFRAMEs are replaced with rainbow colored boxes.
Attached below.

But it does not work for <img> images, they show ip as empty boxes instead.

Can you share your solution with me?

squid.conf:
...
acl ads_regex url_regex -i [./]banners*[./?]
acl ads_regex url_regex -i [./]bannerserver[./?]
acl ads_regex url_regex -i [./]bannerbank[./?]
acl ads_regex url_regex -i [./]bannerfarm[./?]
acl ads_regex url_regex -i \.linkexchange\.ru:*[0123456789]*/
acl ads_regex url_regex -i [./]adv[./?]
acl ads_regex url_regex -i /count.*\?
acl ads_regex url_regex -i /ping.*\?
acl ads_regex url_regex -i [./]adserver
acl ads_regex url_regex -i /phpAdsNew.*/ad.*\.php\?
acl ads_regex url_regex -i /adsystem.*/ad.*\.php\?
...etc etc etc...
...
http_access deny ads_regex
...
