Hi, I am using Squid 2.7.STABLE7 on Debian Squeeze (testing). I use delay pools to limit download rates to individual users. But, when using url_regex with exclamation mark, it doesn't work. It worked fine in previous versions. An example: acl geral url_regex -i .* !\.htm !\.html !\.php !\.txt !\.jhtm !\.shtml !.*.acc\.umu\.se.* After start a download from *.acc\.umu\.se.*, the cache.log shows: 2010/06/16 09:48:37| aclMatchRegex: match '.*' found in 'http://caesar.acc.umu.se/cdimage/daily-builds/daily/arch-latest/i386/iso-cd/firmware-testing-i386-netinst.iso' So, the requested URL matched with .* and wasn't excluded by !.*.acc\.umu\.se.*. Is it a bug? Thanks in advance. Regards, Eriberto - Brazil
