No Permission for Loading

I have two swf files. One of them is holder and one of them is a child swf.

The codes in holder swf:

////////////////////////////////////////////////
var loader:Loader = new Loader();
loader.load(new URLRequest("link.swf"));
addChild(loader);
////////////////////////////////////////////////

The codes in holder swf(named link.swf):

getURL("http://www.somelink.com/","_self");

Here what I want:
I don’t want link.swf to connect to internet.I mean I dont want to let it to link other websites, or load another files(php,xml ext…).

How can I do it? For example Deviantart solved this problem for their security. I send a mail them but they don’t give me answer…

How can I solve this? Thank you

Come on guys… There must be a someone who knows this.
