HTTP cookie


(n.) Hypertext Transfer Protocol cookie; a packet of data that is sent by an HTTP server to a web browser, is stored on the client computer, and is returned by the browser each time it accesses the server that sent the cookie. Cookies may contain any kind of data that the server chooses to send, but they are primarily used to inform the server of the state of the browser and the configuration of the client. A cookie can be used by a server to identify a registered user of a site in order to avoid asking for a password on each visit.
