Example Code – 1 – Forcing the domain to serve securely using HTTPS (for any site)

Example Code - 1 - Forcing the domain to serve securely using HTTPS (for any site)# The following forces any http request to be rewritten using https. For example, the following code forces a request to http://example.com to load https://example.com. It also forces directly linked resources (images, css, etc.) to use https:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]

or

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301,NE]
