Hi friends, I am running a squid proxy server in transparent mode on FC7 (squid-2.6.STABLE16-2). Currently 15 MB download limit is set in the squid but I want to restrict download of certain file types based on the size for ex if the size of .mp3/mpeg file is more than 1MB then don't allow the file to be downloaded but allow other file types to be downloaded with 15MB download limit. I tried the below settings in squid.conf file acl ankush src 172.16.4.0/24 (network range) acl ankush1 src 172.16.4.0/24 http_access allow ankush acl block_stream urlpath_regex \.(ra?m|mpeg|mov|m3u|pls|ivf|asf|asx|avi|wax|wma|wmv|wvx|wmp|wmx|m1v|mp2|mp3|mpa|mpe|mpv2|rm)($|\?) acl streaming rep_mime_type ^video/x-ms-asf ^video/x-ms-sf ^audio/mpeg ^audio/x-mpeg ^audio/x-pn-realaudio ^application/x-mms-framed ^application/vnd.ms.wms-hdr.asfv1 OPTIONS FOR X-Forwarded-For reply_body_max_size 15000000 allow ankush(15 MB Limit for downloading) reply_body_max_size 1000000 allow ankush1 streaming block_stream (only allowing 1MB for movie/video files) But still I am able to download movies/video files greater than 1 MB. Any suggestions/comments are most welcome. Thanks & Regards Ankush
