The easiest way for me would be to tell Squid that it's just a list of exact URLs, not a list of regexps. I understand that's not possible. This list comes with entries such as: https://domain.org/?something={whatever}&other=(this) So, if I don't want Squid to complain I process it a little before serving it to it and the above line becomes: https://domain.org/\?something=\{whatever}&other=\(this) You mention anchoring them... So now I adjusted the processing and the above becomes: ^https://domain.org/\?something=\{whatever}&other=\(this)$ I'm still getting the same denial when a client tries to access https://www.google.com/. This is what I can see in cache.log: client_side_request.cc(751) clientAccessCheckDone: The request GET https://www.google.com/ is DENIED; last ACL checked: bad_dst_urls I'm also seeing other denials such as: client_side_request.cc(751) clientAccessCheckDone: The request GET http://www.microsoft.com/pki/certs/MicRooCerAut2011_2011_03_22.crt is DENIED; last ACL checked: bad_dst_urls If I grep http://www.microsoft.com/pki/certs in the ACL file I get no results at all. That's why I'm puzzled. So here's the new anchored regex file in case you have the chance to test it and reproduce the issue: https://drive.google.com/file/d/1ZUP9eRAqLzMG162xHfYRV9vx_47kWuXs/view?usp=sharing Squid doesn't complain about syntax errors so I'm assuming the ACL is as expected.
