PHP for removing www from request and redirecting. (Useful for System.security.allowDomain issues) (See related posts)

<?
	// if www.domain.com, redirect to domain.com
	if (strtolower(substr($_SERVER['HTTP_HOST'], 0, 3)) == "www") {
		header("Location: http://rgcreative.com" . $_SERVER['REQUEST_URI']);
	}
	
	// Full path to current URL (including query string)
	//echo "http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
?>
