Crossdomain.xml Not Loading

Question

This may be a newb question. I’m trying to figure out why my swf file, running from localhost, is bypassing the crossdomain.xml when loading a xml file from a remote domain.
I stored the crossdomain.xml at the root of the domain.
http://www.mydomain.com/crossdomain.xml
When I checked the HTTP headers, there’s no request sent out to get the crossdomain.xml file.
Another issue is that the Security.sandboxType is always localTruested. Could that be the reason that the swf file is not checking the crossdomain.xml? If so, how can i change the sandboxType.
Any help is appreciated!
Thanks

Can you look at the name of the file you're loading before you load it? So, if it contains .swf don't load? Aside from that, you can get the content type before the image/file is finished loading. You do it with the LoaderInfo object... something like this:
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.INIT, initHandler);
function initHandler(event:Event):void {
    var loader:Loader = Loader(event.target.loader);
    var info:LoaderInfo = LoaderInfo(loader.contentLoaderInfo);
    trace(info.contentType);
If you load a jpeg you will see: image/jpeg
If you load a .swf you will see: application/x-shockwave-flash
