Flash :: Why Do URLReqeusts Not Load Files When Move Them To A Web Server

When developing a flash project on my machine I can use something like:

var request:URLRequest = new URLRequest("images.xml");
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, handleResult);

[Code]....

As long as the images.xml file is located in the same directory as the .fla then it works fine. However once I move the .swf, .xml and my images to the web it all goes down the drain. The .swf can no longer find the .xml file and I know why. Using FlashBug I can read the error in the console.

IOError: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: http://www.mydomain.com/images.xml"]

And there's the problem when I move my .swf to my web server the URLRequest adds my domain to the request. Since the file was just located in the same directory on my machine it didn't cause an issue to just say "images.xml" but now in order to make it work I have to change it to [URL]

I want to know if there is a way to force the .swf to just continue to look in the directory it is in for the files it needs. I think having to spell it out is counter-intuitive because then I can't just move the files without having to re-write my AS3 code.
