How to force HTTPS using the .htaccess file

Sometimes it's necessary to make sure your website’s visitors use the SSL encrypted connection. If you’re not familiar with SSL and would like to know more please review our article “What is SSL and Why is it important?” If you need assistance using the shared SSL that InMotion Hosting offers to shared hosting customers, please see our article on "forcing your visitors to use the shared ssl".

Forcing visitors to use SSL can be accomplished through your .htaccess file using mod_rewrite. If you’d like more information on mod_rewrite please read our article.

To 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 .htacess, add this above where there are already rules with a similar starting prefix.

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.example.com/$1 [R,L]

Be sure to replace www.example.com with your actual domain name.

To force a specific domain to use HTTPS, 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.example.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.example.com with your actual domain name.

If you want to force SSL on a specific folder you can 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.example.com/folder/$1 [R,L]

Make sure you change the folder reference to the actual folder name. Then be sure to replace www.example.com/folder with your actual domain name and folder you want to force the SSL on.
