How to Force HTTPS on a Specific Domain

Let’s say that you have two domains: http://yourdomain1.com and http://yourdomain2.com. Both domains access the same website, but you only want the first one to be redirected to the HTTPS version. In this case, you need to use the following code:

RewriteEngine On

RewriteCond %{HTTP_HOST} ^yourdomain1.com [NC]

RewriteCond %{HTTPS} off

RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Make sure to replace yourdomain1 with the actual domain you’re trying to force HTTPS on.
