HTTP cookies allows a web page to "remember" certain actions executed by the user. A classic example of maintaining a given state is a shopping cart application. The user travels from one product review to the other, and clicks a button to drop an item in his or her "shopping cart." The user-specific data is stored by the browser using cookies.
