Modify the session expires after closing the browser:

1. Add Session_expire_at_browser_close=true on the last line of settings.py
2. Empty the saved Session:delete from Django_session
3. Empty IE Cache
4. Re-test OK, use Print request.session.get_expire_at_browser_close () to see if the session expires after the browser is closed
