May I ask if you are Intercepting the connections or in your setup you
define/configure in the browserclient the proxy settings?

Dear all,
currently I try to configure peek-and-splice on Centos7 and squid4. I have a
running config for Centos6.6 and squid 3.5.18.
No matter what I try i can't get squid4 to splice certain sites and to
bump/terminate the rest. My config is as follows:
acl sni_exclusions ssl::server_name .google.com
acl sni_exclusions ssl::server_name .google.de
acl tcp_level at_step SslBump1
acl client_hello_peeked at_step SslBump2
ssl_bump peek tcp_level all
ssl_bump splice client_hello_peeked sni_exclusions
ssl_bump bump all
if I replace the ssl_bump bump all with ssl_bump terminate all, all sites are
terminated, if I do a ssl_bump splice all, all https traffic is going through.
the log when a device connects to an allowed site looks is below, if I accept
the self generated certificate access the webpage is allowed. If i do the same
with a site not allowed i'll get redirected to the deny_info page after
accepting the certificate. So everything working as desired besides the
certificate warning for "spliced" websites. I'm using the squid4 build from
http://wiki.squid-cache.org/KnowledgeBase/CentOS#Squid_Beta_release
(http://wiki.squid-cache.org/KnowledgeBase/CentOS#Squid_Beta_release).
Thanks in advance for any hint,
Alex
