What are cookies, and how do they work?

A cookie is a small bit of information that a web site stores on your computer. When you revisit the web site, your browser sends the information back to the site. Usually a cookie is designed to remember and tell a web site some useful information about you.

For example, an online bookstore might use a cookie to record the authors and titles of books you have ordered. When you return to the online bookstore, your browser lets the bookstore's site read the cookie. The site might then compile a list of books by the same authors, or books on related topics, and show you that list.

This activity is invisible to you. Unless you have set your preferences so that you will be alerted when a cookie is being stored on your computer, you won't know about it. When you return to a web site, you won't know that a cookie is being read. From your point of view, in the example above, you'd simply visit the online bookstore, and a list of books that might be of interest to you would magically appear.

An "s" added to the familiar "http" (making it https)
