For example, they are commonly used to authenticate or identify registered users of a website without requiring them to sign in each time they access it. Other uses include maintaining a ′shopping basket′ of goods a user has chosen to purchase, site personalisation (presenting different pages to different users) and tracking the pages a user has visited on a site for analysis purposes.
