Interpreting session activity
If you put some data in request.session it automatically creates a record in django_session on process_response of session middleware. So if you put nothing in the session, and it stores only login data - then it will be number of logins (also by the same user - logount clears session data so it's being recreated if anyone logs in)
I am looking at my table for django_session and would like to know what this essentially means. 
If I have 100 session entries in the past hour, does that mean 100 people have logged in in the past hour? Or does it mean something else?
