What Are Cookies?
A cookie is a very small text document, which often includes an anonymous unique identifier. When you visit a Web site, that site’s computer asks your computer for permission to store this file in a part of your hard drive specifically designated for cookies. Each Web site can send its own cookie to your browser if your browser’s preferences allow it, but (to protect your privacy) your browser only permits a Web site to access the cookies it has already sent to you, not the cookies sent to you by other sites.
