Force SSL On Domain
Force all web traffic to use HTTPS
Insert the following lines of code in the .htaccess file in your website’s root folder.
Important: If you have existing code in your .htaccess, add this above where there are already rules with a similar starting prefix.
RewriteEngine On
RewriteCond %{SERVER_PORT} 80 RewriteRule ^(.*)$ https://www.yourdomain.com/$1 [R,L]
Be sure to replace www.yourdomain.com with your actual domain name.
Force a specific domain to use HTTPS (v1)
Use the following lines of code in the .htaccess file in your website’s root folder:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^example\.com [NC]
RewriteCond %{SERVER_PORT} 80 RewriteRule ^(.*)$ https://www.yourdomain.com/$1 [R,L]
Make sure to replace example.com with the domain name you’re trying force to https. Additionally, you need to replace www.yourdomain.com with your actual domain name.
Force a specific domain to use HTTPS (v2)
This version works on subdomains too. Just put the code in the root folder of the subdomain.
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
This is the one I’m currently using.
Force SSL on a specific folder
Insert the code below into a .htaccess file placed in that specific folder:
RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteCond %{REQUEST_URI} folder RewriteRule ^(.*)$ https://www.yourdomain.com/folder/$1 [R,L]
Make sure you change the folder reference to the actual folder name. Then be sure to replace www.yourdomain.com/folder with your actual domain name and folder you want to force the SSL on.
