AIR app:How to load swf from server - actionscript-3

Question

My app structure is below:
(local)
Login.swf
(server)
Main.swf
assets1.swf
assets2.swf
Login.swf -> Main.swf (OK!)
Main.swf -> assets1&2.swf (fail!, downloaded but not trigger complete event)
-progress event: bytes:loaded==total
Why?
How can i load assets from server using Main.swf?
I found somebody say it is crossdomain problem...then how to solve?
var _loader:Loader = new Loader();
var context:LoaderContext = new LoaderContext();
context.allowCodeImport = true;
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loader_complete_handler);
_loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loader_progress_handler);
_loader.loadBytes(_urlloader.data,context);
Thanks!

BE AWARE:
On mobile it only works on Android... iOS due to a security policy does not permit to load an swf inside another one.
Said that you can surerly load an SWF.
First of all we need to understand if you can download the SWF bytearray using the URLLoader.
if yes you can load the swf in a two step routine..
hope this help :)
