Answer to Question #96899 in HTML/JavaScript Web Application for Lorraine Motlokoa

Question

What is the difference between cookies and session? In what circumstance should someone use
cookies or session? Support your answer with practical Examples.

Answer 1

Cookies are data that the server can leave at the client (browser). Clearly: 

A client arrives, asks the server for a page.

The server in the response headers can set cookies. For example, issuing two headers: Set-Cookie: foo = 123 and Set-Cookie: bar = baz - i.e. - "remember, foo - 123, and bar - baz".

At the next call the client, if he decided to remember, tells the server "Cookie: bar = baz; foo = 123. "

A session is something that allows you to distinguish one user from another, and usually stores this data somewhere. For example, remember an authorized user.
