How to redirect all HTTP requests to HTTPS

Question

I\'m trying to redirect all insecure HTTP requests on my site (e.g. http://www.example.com) to HTTPS (https://www.example.com). I\'m using PHP btw.

Answer 1

It works for me:

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

and for example, http://server/foo?email=someone%40example.com redirects normally without any issues. The file .htaccess located in the website root folder (for example named public_html). It is possible to use RewriteCond %{SERVER_PORT} !^443$ instead RewriteCond %{HTTPS} !on
