What is a web session and how are cookies involved?

• A. A web session is a period of interaction with a website; cookies store session identifiers so the site can remember you as you navigate pages.
• B. A web session is a saved copy of a page for offline viewing.
• C. Web sessions are only used for authentication and do not involve cookies.
• D. Cookies terminate a session when the browser closes.

Answer: (A)

A web session is the period of interaction with a website from when you first visit (or log in) to when you leave. HTTP doesn’t remember who you are from one page to the next, so a session creates continuity by assigning a unique identifier to you and keeping track of your state on the server. Cookies are small data files stored in your browser that can hold that session identifier. When you navigate pages, your browser sends the cookie with each request, the server reads the session ID, and then fetches your stored session data so the site knows who you are, what you’re signed in to, and other ongoing details like items in a shopping cart. So the idea isn’t just about authentication; a session covers the ongoing interaction across multiple pages, and cookies are the mechanism that carry the session ID between requests to keep everything connected.
