How to configure squid.conf to whitelist both http and https at the same time?

Raised a transparent proxy squid 3.5.8 in the organization to restrict access to sites, ideally it should be done so that you can only go to 2 https sites and 2 http. The proxy is transparent, works with http and https, the below config works fine in the blacklist scenario, cuts out all recorded sites. But I can’t imagine how to convert the config so that everything works exactly the opposite, if you change
http_access deny whitelist to http_access deny !whitelist and
ssl_bump terminate blocked to ssl_bump terminate !blocked
, then only http traffic filtering works properly, and if the line
http_access deny !whitelist
put after
http_access allow localnet, and not before it, then only https traffic filtering rules work correctly.
In general, I'm confused in one pine, help someone) Squid config
:
acl localnet src 2.2.2.0/24
acl SSL_ports port 443
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 # https
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT

Straight postman Pechkin. I have a solution. But I won't tell you .. Only in the ru segment I meet "understood, the issue is closed." without describing the solution itself. "ssl_bump terminate !whitelist" option doesn't work while "http_access deny !whitelist" is active
