StageWebView basic authentication

Hello,

I am using a StageWebView to request a page which requires basic authentication. The documentation on this page: http://helpx.adobe.com/air/kb/stagewebview-differences-platforms-air-sdk.html

states that no authentication dialog is implemented for iOS and Android.

Currently no default UI is implemented on mobile for HTTP authentication. On desktop HTTP authentication uses the default OS dialog for authentication.

Then the docs say it is possible to create your own dialog.

Event though the authentication dialog is disabled, the developer can create their own UI and use the URLRequest API to do basic or digest authentication.

I tried to find a way to implement this but I can't come up with a good solution. What I tried:

1. Try to add headers to the StageWebView requests, not possible, no way to inject.

2. Try to request the url with a URLLoader but no session information is shared between the URLLoader and the StageWebView.

Does anybody have any ideas how to handle the authentication ?
