define('HTTP_SERVER', 'http://www.hailusa.com');
define('HTTPS_SERVER', 'https://www.hailusa.com');

Made that minor change and jackpot! It worked!!!
I've been testing and everything seems fine...
I know that sometimes it can be difficult to answer basic questions to new users but believe me when I tell you, we all appreciate it!!
Thanks for all the help!!
