Вот здесь приводится такой пример:

# os.getenv() enables configuration through OS environment variables

return app

if __name__=='__main__':
app = create_app()
app.run(host='0.0.0.0', port=5000, debug=True)
Если запустить
python user.py
Все стартует и работает.
Но сессия истекает по закрытию браузера.
Добавления:
app.permanent_session_lifetime = timedelta(days=365)
Не помогают.
Как это можно победить?
