         ### Sessions expire when the user closes the browser ###
  
### add this line in settings.py ###
SESSION_EXPIRE_AT_BROWSER_CLOSE = True

---------### Sessions expire after a period of inactivity ###------------------
  						### Fisrt way ###
  
### 1- set a timestamp in the session on every request ###
request.session['last_activity'] = datetime.now()
### 2- add a middleware to detect if the session is expired ###
### Note => search how to add a middleware ###
class SessionExpiredMiddleware:
    def process_request(request):
        last_activity = request.session['last_activity']
        now = datetime.now()

        if (now - last_activity).minutes > 10:
            # Do logout / expire session
            # and then...
            return HttpResponseRedirect("LOGIN_PAGE_URL")

        if not request.is_ajax():
            # don't set this for ajax requests or else your
            # expired session checks will keep the session from
            # expiring :)
            request.session['last_activity'] = now
            
---------### Sessions expire after a period of inactivity ###------------------
  						### second way ###
          
### add these lines in settings.py ###
SESSION_EXPIRE_AT_BROWSER_CLOSE = True
SESSION_COOKIE_AGE = 10 # set just 10 seconds to test
SESSION_SAVE_EVERY_REQUEST = True # whenever you make new request, It saves the session and updates timeout to expire
### A session expired when you close the browser even if SESSION_COOKIE_AGE set ###
### Only when you are idle for more than 10 seconds, the session will expire ###
