About cookies
Cookies are small pieces of text that are stored by your browser. Each cookie has a name and is associated with a particular site. When your browser sends a request to a site (for example, to download a page, image, or video), the computer that responds (known as a server) may tell your browser to set one or more cookies. When your browser makes further requests to the same site it sends the cookies back to the server. This allows the server to remember you as you browse the site, and provide features such as shopping baskets or password-protected areas.
