Recall & Review

What is a session in Django?

A session in Django is a way to store information on the server side about a user across multiple requests. It helps keep track of user data like login status or preferences while they browse the site.

Why do we need sessions instead of just cookies?

Cookies store data on the user's browser, which can be changed or deleted. Sessions keep data on the server, making it safer and more reliable for storing sensitive info like login details.

How does Django identify a user's session?

Django uses a session ID stored in a cookie on the user's browser. This ID links to the session data saved on the server, so Django knows which data belongs to which user.

What kind of data can be stored in a Django session?

You can store any small pieces of information like user preferences, shopping cart items, or login status. It should be data that helps personalize or manage the user's experience.

How do sessions improve user experience on a website?

Sessions let the website remember who you are and what you did, so you don’t have to log in every time or lose your shopping cart. This makes browsing smoother and more personal.

What does Django use to link a user to their session data?

A A session ID stored in a cookie

B User's IP address

C Browser history

D User's email address

Django stores a unique session ID in a cookie on the user's browser to identify the session data on the server.

Where is session data stored in Django?

A On the user's browser

B In the HTML code

C On the server

D In the URL

Session data is stored securely on the server, not on the user's browser.

Why are sessions safer than cookies for storing sensitive data?

A Sessions encrypt data on the browser

B Sessions store data on the server, reducing risk of tampering

C Cookies never expire

D Cookies are hidden from the user

Sessions keep data on the server, so users cannot easily change or see sensitive information.

Which of these is a common use of sessions in Django?

A Changing website colors

B Loading images faster

C Storing large files

D Tracking user login status

Sessions are often used to remember if a user is logged in during their visit.

What happens if a user deletes their cookies related to sessions?

A The user loses the link to their session data and may need to log in again

B The session data on the server is deleted

C The website stops working

D The user’s browser crashes

Deleting cookies removes the session ID, so the server can’t identify the user’s session.

Explain in your own words why sessions are important in web applications like those built with Django.

Think about how websites remember you when you log in or add items to a cart.

Describe how Django uses cookies and sessions together to keep track of a user.

Focus on the role of the cookie and the server in managing sessions.
