Hi, I'm having some trouble with ACLs when I try to block .exe files. Actually the acl works very well, but some sites use .exe files do display html content. I have a few webmail sites and some bank sites that do this. The problem is that I can't figure out how to unblock them. From what I know, squid reads acl rules from top to botton so if I have specified a site to be allowed first, even if there is a blocking rule below it should ignore it. Below are the related acl rules. The first 4 lines are ntlm group based rules. The goodextensions acl is the one that should allow sites with webmail.exe. Instead of letting it go, squid returns me, for ex. that access to the site http://email.terra.com.br/cgi-bin/webmail.exe? is denied. Does anyone know what I'm doing wrong? I'm using squid version 2.5.STABLE9. Any help will be much appreciated.
