Hello folks! I have a "squid 2.5 Stable 12" and I'm trying to do "application blocks" to zip, exe and MSN Messenger 7.5 connections. I need of a special squid compilation to this? My Squid version: ================= Squid Cache: Version 2.5.STABLE12 configure options: --enable-x-accelerator-vary --enable-ssl --enable-pf-transparent --enable-snmp --enable-carp '--enable-storeio=ufs diskd' The MSN ACL: ============ acl MSN_Free srcdomain "/etc/MSN_Free.txt" acl msntime time M T W H F A 11:59-12:59 acl msnq req_mime_type ^application/x-msn-messenger$ acl msnp rep_mime_type ^application/x-msn-messenger$ http_reply_access allow msnp msntime http_reply_access allow msnq msntime http_access allow msnp MSN_Free http_reply_access allow msnq MSN_Livre http_access deny msnp http_reply_access deny msnq ## BLOCKING requested mime types acl exec_zip_free srcdomain "/etc/Exec_Zip_Free.txt" #acl mimeblockREQ req_mime_type ^application/zip$ acl ZipBlock url_regex ^http://*application\/zip* acl mimeblockREP rep_mime_type ^application/zip acl mimeblockREQ req_mime_type ^application/x-zip-compressed$ acl mimeblockREP rep_mime_type ^application/x-zip-compressed acl mimeblockREQ req_mime_type ^application/octet-stream$ acl mimeblockREP rep_mime_type ^application/octet-stream acl mimeblockREQ req_mime_type ^application/x-msdownload$ acl mimeblockREP rep_mime_type ^application/x-msdownload http_access allow mimeblockREQ exec_zip_livre http_reply_access allow mimeblockREP exec_zip_livre http_access deny mimeblockREQ http_reply_access deny mimeblockREP http_access deny ZipBlock My Log File: ============ # tail -f /usr/local/squid/var/logs/access.log 1133380440.962 512 10.1.4.11 TCP_MISS/200 352 POST http://207.46.1.11/gateway/gateway.dll? - DIRECT/207.46.1.11 application/x-msn-messenger I think that: TCP_MISS isn't wrong here?
