Reply To: WordPress SSL htaccess code – Rewrite SSL, RewriteCond %{SERVER_PORT}

Load Balancers and SSL Redirect

If Apache is behind a Load Balancer , Pound, HaProxy, Nginx.

Then your  requests coming from the load balancer arrive over HTTP to Apache, so the HTTPS variable is set to OFF. Therefore, .htacess is reading HTTPS OFF from the server.

However, Apache Server does have a SSL variable called HTTP_X_FORWARDED_PROTO that can be used.

#WP REWRITE LOOP START for Load Balancers
RewriteCond %{HTTP:X-Forwarded-Proto} !https 
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] 

or

#WP REWRITE LOOP START- For Load Balancers
RewriteEngine on
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
