public class OAuthCallbackServlet
extends InjectedServlet

Servlet to act as our OAuth callback URL. When gadget authors register a consumer key with an OAuth service provider, they can provide a URL pointing to this servlet as their callback URL. Protocol flow: - gadget discovers it needs approval to access data at OAuth SP. - gadget opens popup window to approval URL, passing URL to this servlet as the oauth_callback parameter on the approval URL. - user grants approval at service provider - service provider redirects to this servlet - this servlet closes the window - gadget discovers the window has closed and automatically fetches the user's data.
