RewriteCond A or (!B and !C) - apache

Question

I can use mod_rewrite in .htaccess file on Apache server. I'd like to have something like this:
RewriteEngine On
RewriteCond %{HTTPS} !on [NC,OR]
RewriteCond %{HTTP_HOST} !^example\.com
RewriteCond %{HTTP_HOST} !^sub\.example\.com
RewriteRule ^/?(.*)$ https://example.com/$1
while meaning "if http or request subdomain other than sub.(e. g. www.), redirect to https and without www.".
https://example.com --> do nothing
http://example.com --> https://example.com
https://www.example.com --> https://example.com
http://www.example.com --> https://example.com
https://sub.example.com --> do nothing
http://sub.example.com --> https://sub.example.com, this will definitely not work with code above
What's the simplest way to do this? Thanks in advance!

Answer 1

You need to break this into 2 different rules:
RewriteEngine On
# remove www and https for https://www.example.com or http://www.example.com
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [L,NE,R=302]
# simply add https for rest
RewriteCond %{HTTPS} !on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,NE,R=302]
Make sure to clear your browser cache or use a new browser for testing.
Change 302 to 301 after testing.
