Cached session backend

By default, Django stores its user session in the database. This usually gets retrieved for every request. To improve performance, the session data can be stored in memory by changing the SESSION_ENGINE setting. For instance, add the following in settings.py to store the session data in your cache:

SESSION_ENGINE = "django.contrib.sessions.backends.cache" 

Since some cache storage can evict stale data leading to the loss of session data, it is preferable to use Redis or Memcached as the session store, with memory limits high enough to support the maximum number of active user sessions.
