Suddenly it turned out that it's impossible to deny video from www.rutube.ru by Squid means. There is the only intend to cut off video, not shockwave nor java-scripts. Rutube.ru uses inframe incapsulation of video via java-script. Example: http://rutube.ru/tracks/4567054.html piece of code: <script type="text/javascript"> var rt_referer = escape(location.href); playMovie('pid', 'http://rutube.ru/player.swf?buffer_first=1.0&file=http%3A%2F%2Fbl.rutube.ru%2Fdb9decb3ae2341724c72e6490b028cfd.iflv&xurl=http%3A%2F%2Frutube.ru%2Ftrackinfo%2Fdb9decb3ae2341724c72e6490b028cfd.html%3Fad_ids%3D&image=http%3A%2F%2Ftub.rutube.ru%2Fthumbs%2Fdb%2F9d%2Fdb9decb3ae2341724c72e6490b028cfd-1.jpg&&autoload=true&fsb=true&logo=false&newWnd=false&rAngle=0&uid=3692805&referer=' + rt_referer); </script> So it freely passes through rep_mime_type, rep_header, url_regex (). Please, give me solution how Squid and/or SquidGuard could cut off video, not disabling access to site itself. Approach is to deny video content, not site itself. NB Using rep_mime_type, rep_header, url_regex works fine with youtube.com - it lets to download shockwave player, but player is unable to download and play video. Thank you in advance. Looking forward to the closest friendliness of Squid+SquidGuard as www.gfi.com (MS ISA srv+GFI WebMonitor) give.
