A cookie is a small amount of data that can be transmitted by a web server to your browser when you visit a web site. Web sites use cookies to remember details about you, such as your user name or site preferences, in order to personalize your experience on that web site. Your browser will transmit information back to the site each time you view that site until the cookie expires. Manually deleting cookies may solve problems with web sites or with the browser itself. Learn more.

You can set your browser's preferences to accept or reject cookies or notify you when a cookie is set. Your computer generally stores a cookie as a small text file that the server can recover if you return to that web site later; other cookies are temporary and allow the server to remember information about you only until you close your browser.
