Hello, I have a proxy configured to bump all traffic in order to do traffic filtering to a target server (Artifactory, in my case) from a particular environment. The proxy needs to be able to allow or permit traffic based on the path part of the URL in order to only allow access to a certain set of Artifactory repositories. I have my proxy configured to bump all traffic so that the urlpath_regex ACL can be applied, but it appears to not have any effect post-bump. I have dug through the debug logging and it evaluates the ACL before the bump occurs, but not after. I know it's bumping and decrypting the request properly because the access logs shows the information I need, but it's not actually applying the ACL. Can anybody provide recommendations as to what I might be doing wrong? My (highly simplified, to remove possible points of failure) squid.conf is provided below, as well as the debug logs from a couple of sample requests.
