Cookies are small data structures delivered by a Web site to a Web client.
The Web site may deliver one or more cookies to the client. The client stores cookie data in one or more flat files on its local hard drive. Cookies help us evaluate visitors' use of our site, such as what customers want to see and what they never read. That information allows us to better focus our online product, to concentrate on information people are reading and products they are using. Cookies are designed to be read only by the site that provides them, not by other sites.
