Using X-Forwared-Proto

Hello, I had a problem with “Too many redirects” with my wordpress site sitting behind a reverse-proxy so I checked the .htaccess file contents:

# BEGIN HTTPS Redirection Plugin
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
# END HTTPS Redirection Plugin

I was surprised to see that this file 1. Does not support reverse-proxies 2. Uses the port as a proxy to check the protocol.

Please note that the %{HTTPS} variable checks for the actual use of the HTTPS protocol and %{HTTP:X-Forwarded-Proto} must be checked to support reverse-proxies.

With the correct changes, the .htaccess file looks like this

# BEGIN HTTPS Redirection Plugin
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
# END HTTPS Redirection Plugin
