如何从Dreamweaver发现PHP

How can I discover if a called to PHP is made from Dreamweaver to check a file s correct?

Like one of my is called Utilities.php. Dreamweaver makes Utilities_3ooftqaeu3.php and sends it to PHP.

My problem is in my code I execute

header( "location: ".$_SERVER['SCRIPT_NAME']);

and because Utilities_3ooftqaeu3.php doesn't exist Dreamweaver reports an validation error.

Is there a way out of this? The easiest would be if I could recognise that Dreamweaver has made the call to PHP and then not execute header() command
