How to use beaker with GAE

Question

Hi I'm going to use an own session object and I'm trying to apply beaker with python. Can you tell me how to use it with google app engine? I've got the following code and then I'm unsure how to proceed:

    session_opts = {
        'session.cookie_expires': True,
        'session.type': 'ext:google',
        'session.key': 'mykey.beaker.session.id',
    }

    def main():
        logging.getLogger().setLevel(logging.DEBUG)

        application = webapp.WSGIApplication([(...
... handlers          ],debug=True)
        application = SessionMiddleware(application, session_opts)

        util.run_wsgi_app(application)
