        string absoluteUri = string.Format("{0}://{1}", Request.Url.Scheme, Request.Url.Authority);
        var service = BaseOauth2Service.GetService(id, absoluteUri);

        if (service != null)
        {
            var url = service.BeginAuthentication();
            return Redirect(url);
        }
        else
        {
            return RedirectToAction("LoginFail");
        }
    }

    public ActionResult Callback(string id)
    {
        string absoluteUri = string.Format("{0}://{1}", Request.Url.Scheme, Request.Url.Authority);
        var service = BaseOauth2Service.GetService(id, absoluteUri);

        if (service != null)
        {
            BaseUserData userData = null;
            var redirectUrl = service.ValidateLogin(Request);

            switch (id)
            {
                case "Facebook":
                    userData = service.GetUserInfo<FacebookUserData>();
                    break;
                case "Google":
                    userData = service.GetUserInfo<GoogleUserData>();
                    break;
                case "Twitter":
                    userData = service.GetUserInfo<TwitterUserData>();
                    break;
            }

            if (redirectUrl != null)
            {
                return Redirect(redirectUrl);
            }

            return RedirectToAction("LoginSuccess");

        }
        else
        {
            return RedirectToAction("LoginFail");
        }
    }

    public ActionResult LoginFail()
    {
        return View();
    }

    public ActionResult LoginSuccess()
    {
        return View();
    }
}
