Apache Configuration Question

htaccess force https and redirect www to non-www, but no other subdomains

I know there are many similar threads, but none of them seems to match my exact problem. Here is what I’m trying to do:

(1) http://www.mydomain.com/ -> https://mydomain.com/
(2) http://mydomain.com/ -> https://mydomain.com/
(3) https://www.mydomain.com -> https://mydomain.com/


Ideally, I would also like to cover the situation if I will ever add more subdomains, to automatically behave like the following (preferably in a generic way that will work for any subdomain I add).

(4) http://sub.mydomain.com/ -> https://sub.mydomain.com/


At this point I’m wondering if it is even possible to create a single .htaccess file that does everything I need, although I have to admit that I understand regexes, but I’m not exactly a mod_rewrite uberpro.

Here are the solutions that I already tried:



My SSL certificate covers the www-subdomain, so I’m not looking for a 'untrusted connection' error solution, I’m aware that isn’t possible.

Answer

Put this code in your DOCUMENT_ROOT/.htaccess file:

RewriteEngine On

RewriteCond %{HTTPS} off
RewriteCond %{ENV:HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301,NE]

RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [L,R=301,NE]
