        Parameters:
        browser - The corresponding browser.
        frame - The frame generating the event. Instance only valid within the scope of this method.
        request - The request itself. Cannot be modified in this callback. Instance only valid within the scope of this method.

        isDownload - True if the resource request is a download.
        requestInitiator - The origin (scheme + domain) of the page that initiated the request.
        disableDefaultHandling - Set to true to disable default handling of the request, in which case it will need to be handled via CefResourceRequestHandler.getResourceHandler or it will be canceled.
