Web API Development with Flask (Video 20)

This video tutorial covers the use of cookies in Flask applications. It begins with an introduction to cookies, explaining their role in client-server communication. The video then details various types of cookies, such as secure, HTTP only, session, and persistent cookies, and their specific uses. Practical implementation in Flask is demonstrated, including setting and retrieving cookies. The tutorial concludes with a summary and a preview of the next topic, which will focus on password storage and validation.

What is a potential risk of storing sensitive information in cookies?

• Cookies can be accessed through JavaScript.

• Cookies can be easily deleted by the user.

• Cookies can only store text data.

• Cookies are not supported by all browsers.

Which type of cookie must be transmitted over a secure channel like HTTPS?

• Persistent cookie

• HTTP-only cookie

• Session cookie

• Secure cookie

What is a characteristic of HTTP-only cookies?

• They are only used for HTTP and HTTPS requests.

• They can be accessed through JavaScript.

• They do not require a secure channel.

• They are stored permanently on the client side.

In a Flask application, how is a new cookie set in the response?

• By sending a special HTTP header.

• By directly modifying the client's browser settings.

• Using the set_cookie method of the response object.

• Using the set_cookie method of the request object.

What happens when you navigate to the candidate screen in the Flask application example?

• The cookie is deleted from the server.

• A new cookie is created and sent to the client.

• The cookie value is printed on the client side.

• The cookie is sent from the client to the server and logged.
