I created a file called "bad_strings.acl" wich are words that are associated to porn content and for words that can be associated to potential hazardous sites on the web, like hack, warez etc. Everything seemed to be working fine until except for the Yahoo! Mail. Some people on the network use Yahoo! Mail (http://login.yahoo.com/config/mail?.intl=br) and the login site opens Ok but the problem is: When I have the word ass, Squid blocks the login process with this response: ERROR The requested URL could not be retrieved ---------------------------------------------------------------------------- ---- While trying to retrieve the URL: http://us.rd.yahoo.com/reg/login0/no_suli/login/br/ym/*https://login.yahoo.com/config/login? The following error was encountered: Access Denied. Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect. But if I take the word "ass" out of the "bad_strings.acl" it works fine. I searched for the string ass anywhere in that url and found nothing. Has anybody encountered this problem before? Anyway: By commenting or erasing that line from the "bad_strings.acl" Yahoo! Mail works fine. But I would like to make it work with that string on the file.
