Hello folks, I'm running squid 2.6 stable 21 on Centos 5.4 Enterprise, in my network, many people want to download very large files with special pattern in url. Then I use acl to deny these special character with url_regex but it seems does not work. acl something url_regex abc or acl something url_regex *abc or acl something url_regex \.abc ..... does not work. Please help. Thanks!
