I want to implement login and logout session in my website through which after a set of time the session should expire automatically. And if user logged in then the user could not go back.
In your settings.py
set https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-SESSION_COOKIE_AGE.
For example if you want time out to be one hour
SESSION_COOKIE_AGE = 3600 # one hour in seconds
