Question

I have the following htaccess code:

RewriteEngine On
RewriteCond !{HTTPS} off
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{RE         


        

Answer 1

To redirect http:// or https:// to https://www you can use the following rule on all versions of apache :

RewriteEngine on

RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^ https://www.example.com%{REQUEST_URI} [NE,L,R]

Apache 2.4

RewriteEngine on

RewriteCond %{REQUEST_SCHEME} http [OR]
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^ https://www.example.com%{REQUEST_URI} [NE,L,R]

Note that The %{REQUEST_SCHEME} variable is available for use since apache 2.4 .

Answer 2

If you are using CloudFlare or a similar CDN you will get an infinite loop error with the %{HTTPS} solutions provided here. If you're a CloudFlare user you'll need to use this:

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
