Is squid capable of adding custom SNIs? Like could I have it so gmail.com is added to the certificate as a subject alternate name EVEN though the original certificate doesn't contain it? If such a thing is possible I would love to know the term for it so I can do some searches.
Appreciate it!

Has anyone been able to configure Squid in a way so that if you type https://gmail.com in your browser, you are NOT presented with the "OMG HSTS I refuse to load anything" page? When I go to https://gmail.com, I get an invalid certificate because the cert is for mail.google.com, issued by my CA. If I go to https://mail.google.com, the cert is beautifully green. Why can't squid detect that gmail.com is redirecting my browser to mail.google.com and generate the cert accordingly?
Even configuring an acl for gmail.com doesn't work. It seems like even though I am punching https://gmail.com in my browser, Squid detects it as though I am typing "https://mail.google.com" in my browser and is ignoring any ACLs I have setup specifically for "gmail.com".
I can't be the only one with this issue?
I've also attempted to do:
acl bl1 gmail.com moz.com
always_direct allow bl1 <- from what I understand this bypasses squid and tells my browser to get the cert right from the site. Maybe I am wrong.
But certificates still come from Squid, so I don't see any effect from that line.
Here's my config, lots of garbage in there since I have been trying everything i can think of to get this working. I want to add that for my acl called BL1, the only one that works is moz.com . They are part of the same ACL line, so if one works, they should all work. Except they do not.
Thanks in advance.
