htaccess: Redirect all of your pages to be forced to use SSL
Add this to your .htaccess file.
# Redirect to HTTPS RewriteCond %{HTTPS} off RewriteCond %{HTTP:X-Forwarded-Proto} !https RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
This should be placed directly after RewriteEngine on if you have no previous rewrites.
