Wordpress reverse proxy

When using a nginx reverse proxy to Apache and accessing the Wordpress site using HTTPS it returns a Redirect Error. Adding some lines to wp-config.php fixes it.

After the line define('WP_DEBUG', false) add:

// Reverse proxy patch
if ( $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https' ) {
    $_SERVER['HTTPS'] = 'on';
    $_SERVER['SERVER_PORT'] = 443;
}
