    # Per default django uses the database as session backend. This can be slow.
    # One possibility is to use the cache session backend with redis as cache backend
    # Another possibility is to use a native redis session backend. For example:
    # https://github.com/martinrusev/django-redis-sessions

    SESSION_ENGINE = 'redis_sessions.session'


# When use_redis is True, the restricted data cache caches the data individuel
# for each user. This requires a lot of memory if there are a lot of active
# users. If use_redis is False, this setting has no effect.
