Hi All, my main squid configuration uses somenting like ... [snip] acl nosite url_regex "/etc/squid/etc/nosite" acl site url_regex "/etc/squid/etc/site" acl nosite_city url_regex "/etc/squid/etc/nosite_city" acl site_city url_regex "/etc/squid/etc/site_city" acl src_city "/etc/squid/etc/src_city" ... [snip] ... http_access deny src_city nosite http_access deny src_city nosite_city http_access allow src_city site http_access allow src_city site_city [snip] ... replicated for many city. Regex files contain domain names like ... [snip] .domain1.com .domain2.com [snip] .... Now I should allow 10 videos on youtube site but deny all others. I tried to use "urlpath_regex" and a python script as "redirect_program" but without success. Please can you suggest the best way to do it knowing only the youtube video id? Thanks to all AP OS: Centos 6.5 Squid: squid-3.1.10-19.el6_4, from centos repository
