load Method

public function load(request:URLRequest, context:LoaderContext = null):void

The request parameter of this method accepts only a URLRequest object whose source property contains a string, a class, or a URLRequest object. By default, the LoaderContext object uses the current domain as the application domain. To specify a different application domain value, to check a policy file, or to change the security domain, initialize a new LoaderContext object and pass it to this method.

Parameters
request:URLRequest - The URLRequest object to use to load an image into the scroll pane.
context:LoaderContext (default = null) - The LoaderContext object that sets the context of the load operation.
