I believe this sort of spamming uses the CONNECT method. The default squid configuration prevents this already with: acl SSL_ports port 443 acl CONNECT method CONNECT http_access deny CONNECT !SSL_ports and acl Safe_ports port 80 # http acl Safe_ports port 443 # https acl Safe_ports port 21 # ftp http_access deny !Safe_ports --- Chris Covington IT Plus One Health Management 75 Maiden Lane Suite 801 NY, NY 10038 646-312-6269 http://www.plusoneactive.com
