I have read that. My particular configuration is a bit different... Squid is terminating SSL for several domains. www.domain1.com www.domain2.com foobar.domain1.com The external facing Internet IPs have a destination NAT on an external facing device. IE: www.domain1.com -> 1.2.3.4 -> 10.10.0.50 www.domain2.com -> 1.2.3.5 -> 10.10.0.60 foobar.domain1.com -> 1.2.3.4 -> 10.10.0.50 Example excerpt SQUID 2.6 configuration: https_port 10.10.0.50:443 cert=/etc/squid/keys/wildcard.domain1.com.crt key=/etc/squid/keys/wildcard.domain1.key cipher=RC4-MD5:RC4-SHA:AES128-SHA:DES-CBC3-SHA:AES256-SHA options=NO_SSLv2 transparent https_port 10.10.0.60:443 cert=/etc/squid/keys/www.domain2.com.crt key=/etc/squid/keys/www.domain2.key cipher=RC4-MD5:RC4-SHA:AES128-SHA:DES-CBC3-SHA:AES256-SHA options=NO_SSLv2 transparent url_rewrite_host_header off url_rewrite_program /etc/squid/redirector-https.pl acl TheOriginServer dstdomain www.domain1.com acl TheOriginServer dstdomain www.domain2.com acl TheOriginServer dstdomain foobar.domain1.com http_access allow TheOriginServer http_access deny all Hosts file pointing to internal load balancer IPs: 10.10.0.150 www.domain1.com 10.10.0.150 foobar.domain1.com 10.10.0.160 www.domain2.com Works great. Provides client termination, URI re-writes, and caching of static content. I have been unable to successfully configure Squid 3.3 in a similar fashion. I have been using the new intercept with ssl-bump on the https_port and ssl_bump client-first TheOriginServer. I have tried several different things unsuccessfully. Do you have any thoughts how I can maintain this configuration with Squid 3.3? Please pardon the confidentiality notice message.
