What Is a Cookie?An HTTP cookie, or a Web cookie, is a parcel of text sent by a server to a Web browser and then sent back unchanged by the browser each time it accesses that server. HTTP cookies are used for authenticating, tracking, and maintaining specific information about users, such as site preferences and the contents of their electronic shopping carts. The term "cookie" is derived from "magic cookie," a well-known concept in UNIX computing that inspired both the idea and the name of HTTP cookies.1
Cookies are subject to a number of misconceptions, mostly based on the erroneous notion that they are computer programs. In fact, cookies are simply pieces of data unable to perform any operation by themselves. In particular, they are neither spyware nor viruses, despite the detection of cookies from certain sites by many anti-spyware products.2
Most modern browsers allow users to decide whether to accept cookies, but rejection makes some Web sites unusable. For example, shopping baskets implemented using cookies do not work if cookies are rejected.3
