Squid 3.5.5 I seem to have some confusion about how acl lists are processed in squid.conf regarding the handling of SSL (HTTPS) traffic, attempting to use ssl_bump directives with transparent proxy. Based on available documentation, I believe my squid.conf is correct, however it never seems to

Yuri, The proxy is being used as a content filter, i.e. domain and URL whitelisting and blacklisting. I guess my real question is simply regarding how this traffic is processed in regards to where I've defined options in my squid.conf? Also, why does it appear to bump all sites when my config

Thanks for the response. Our understanding was that by using the peek and splice options, we could transparently filter https traffic using the SNI at the very least (though perhaps the issue lies with our external ACL?), without having to decrypt the SSL session or use MITM cert. Our results in
