A cookie is a file that is downloaded on a user’s computer/smart phone/tablet when accessing certain web pages. It stores and recovers information about the navigation that is done from this machine.
Technically, cookies are arbitrary pieces of data defined by the web server and sent to the browser. The browser returns them to the server without modifying them, thus reflecting a state (memory of previous events) in the HTTP transactions, that in any other way would be independent from this state.
Specifications of cookies suggest that browsers support a minimal number of cookies or a minimum amount of memory to store them. In particular, they expect a browser to be capable of storing at least 300 4 kilobyte cookies and at least 20 cookies per server or domain.
The server that establishes the cookie can specify a deletion date, in which case the cookie will be erased on that date. A shopping site would want to be able to help potential customers to remember the things that were in their shopping cart, even if they close the browser without making the purchase and return later, in order to prevent them from having to look for the products again. In this case, the server would create a cookie with a deletion date according to the wishes of the website’s designer. If there is no deletion date set, the cookie is erased when the user closes their browser. Therefore, setting a deletion date is a way to make the cookie survive between sessions. For this reason, the cookies with a deletion date are called persistent.
