What are cookies and should I accept them from a web site?
Cookies are small text files saved to your hard drive that contain information used by a web site you have visited. Typically, cookies are used for non-threatening purposes like retaining log-in and password information for frequently visited sites so you don’t have to re-enter them each time. They are also used by Web Masters to understand what areas of their site are visited and in what order and by advertiser to determine if a user clicked on an ad to reach a web site.
