I'm working with a SWFLoader to load images. If it tries to load an image from a URL that requires authorization, IE pops up a login dialog. This is particularly annoying when there are many SWFLoaders displayed. I'd like it to quietly fail. I'm calling unloadAndStop() when the 401 response code with a WWW-Authenticate header is returned, which is what causes the popup, but that doesn't work. I'd like to experiment with various request headers, but I can't see any way on the SWFLoader that I can add headers to the request, since it doesn't accept a URLRequest for the URL. Does anyone have any clue about how I might get rid of these popups?
