Apache loop with WordPress and SSL cert installed on a Cloud Load Balancer

  • Terminate SSL onto the CLB
  • Change the main site URL to use HTTPS in the WordPress configuration
  • Add “SetEnvIf x-forwarded-proto https HTTPS=on” in the vhost configuration
  • add these in wp-config: [OPTIONAL]
    define(‘FORCE_SSL_ADMIN’, false);define(‘FORCE_SSL_LOGIN’, false);
    if (strpos($_SERVER[‘HTTP_X_FORWARDED_PROTO’], ‘https’) !== false)
    $_SERVER[‘HTTPS’]=’on’;

  • a good test to make sure PHP is receiving HTTPS are these lines in a test.php file. If should return “on” if PHP is getting HTTPS properly, or if it returns no value, PHP is not aware it’s being called over HTTPS. 
    <?php
printf($_SERVER['HTTPS'])
?>
