Hi Ellezer I have re-compiled squid 4.3 along with the storeid_file_rewrite. (Maybe largefile should be a default config directive!) I added the following to squid.conf store_id_program /usr/local/squid/libexec/storeid_file_rewrite /etc/squid3/storeid_rewrite store_id_children 40 startup=10 idle=5 concurrency=0 store_id_access allow windowsupdate store_id_access deny all My /etc/squid3/storeid_rewrite ^http:\/\/.+?\.ws\.microsoft\.com\/.+?_([0-9a-z]{40})\.(cab|exe|ms[i|u|f]|asf|wm[v|a]|dat|zip|psf|appx) http://wupdate.squid.local/$1 ^http:\/\/.+?\.windowsupdate\.com\/.+?_([0-9a-z]{40})\.(cab|exe|ms[i|u|f]|asf|wm[v|a]|dat|zip|psf|appx) http://wupdate.squid.local/$1 echo "http://download.windowsupdate.com/msdownload/update/common/2014/04/11935736_1ad4d6ce4701a9a52715213f48c337a1b4121dff.cab" | /usr/local/squid/libexec/storeid_file_rewrite /etc/squid3/storeid_rewrite OK store-id=http://wupdate.squid.local/1ad4d6ce4701a9a52715213f48c337a1b4121dff Still need to check it works OK.
