[osflash] Policy Problem

[Sinisa Rudan]

In which way it won't work?

One additional thing related to crossdomain and images.
If you want to access the content of the loaded image from AS (
Loader.content), then you should set the context of load instruction to
check the policy file.
import flash.system.LoaderContext;
context = new LoaderContext();
context.checkPolicyFile = true;
loader=new Loader();
var request:URLRequest = new URLRequest(url);
loader.load(request, context);

If you attempt one of these operations without having specified
checkPolicyFile at loading time, you may get a SecurityError exception
because the needed policy file has not been downloaded yet.

When you call the Loader.load() method with LoaderContext.checkPolicyFileset to
true, Flash Player does not begin downloading the specified object in
URLRequest.url until it has either successfully downloaded a relevant
cross-domain policy file or discovered that no such policy file exists.

All the best,
