How to intercept location URL of StageWebView

Question

Hello !
In my mobile application I'm using StageWebView UI object, instanciated with :
myWebViewObject: StageWebView = new StageWebView;
It displays content from an URL in the page, and it's sized to the screen of the device by defining attributes classicaly. Moreover I need to intercept the location URL just before his removing (when the user exits from this fonctionnality).
I removed it with : myWebViewObject.dispose() ; myWebViewObject.viewPort = null ; myWebViewObject = null .
I tryed to attach several event on the object's instance : Event.CLOSE, Event.CLOSING, Event.UNLOAD, Event.CLOSING, Event.REMOVED, Event.REMOVED_FROM_STAGE.
Anyone can executes callback function successfully !
Do you know the good eventlistener I could use to do that ?
Thanks.

Answer 1

request.getRequestURI() gives me the current page URL. I want URL of the page from which the current page is being called.
I found the following works fine.
request.getHeader("REFERER");
