Hi there: I'm running Squid to block multimedia online using something like this: acl multimedia rep_mime_type -i "/etc/squid/multimedia.txt" http_reply_access deny multimedia-online /etc/squid/acl/multimedia.txt has these lines inside: ^application/vnd.ms.wms-hdr.asfv1$ ^application/x-mms-framed$ ^audio/x-pn-realaudio$ ^audio/mid$ ^audio/mpeg$ ^video/flv$ ^video/x-flv$ ^video/x-ms-asf$ ^video/x-ms-asf$ ^video/x-ms-wma$ ^video/x-ms-wmv$ ^video/x-msvideo$ ^video/x-shockwave-flash$ ^application/x-shockwave-flash$ These rules work fine. Websites like www.enladisco.com or www.atevip.net are displayed normally except the multimedia content (a flash music player) that is correctly blocked. My problem comes here: there are too many websites (I don't know which exactly, maybe 10, 100 or thousands) that display valid content (not online video nor online music) as a "application/x-shockwave-flash" mime type, so they get blocked and end users aren't happy with that. I started to make exceptions to those websites using something like this: acl multimedia-exceptions dstdomain "/etc/squid/webs.txt" http_reply_access allow multimedia-exceptions http_reply_access deny multimedia-online This works OK, but is unmanageable! I can't make exceptions forever just because of application/x-shockwave-flash mime type! www.enladisco.com uses this mime type and it should be blocked because it offers music, but www.xtrema.com.pe doesn't offer online music and is getting blocked when I would not want to block it. Is anybody here having similar troubles with this? Is there any way to block music/video using this mime type? Thanks everyone. P.D.: I'm sorry about my poor english
