Depends on what you want to block there... I assume that you actually mean you want to block HTTPS traffic except to some certain sites. Squid default controls have ACLs called SSL_ports and CONNECT. With this configuration line: http_access deny CONNECT !SSL_ports To restrict further and only allow certain websites to use port 443/HTTPS create an ACL listing their domain names and change the access lien like so acl httpSites dstdomain .example.com http_access deny CONNECT !SSL_ports !httpsSites Amos
