i solved problem using django middleware system , session. think use of session best way guarantee action happens on login (whereas url can reloaded manually).

django sessions not work out of box, implemented own sessions. however, there exists appengine-specific implementation article points out: http://blog.notdot.net/2010/02/webapps-on-app-engine-part-5-sessions

i implemented middleware class this, , added middleware_classes in settings.py:

class loginmanager(object):     def process_view(self, request, view_func, view_args, view_kwargs):         user = users.get_current_user()         if user not none:             marker = session.get(user.user_id())             if marker none:                 login_action()                 session.set(user.user_id(), "true")
