First: CONCEPT OF COOKIES
A cookie is a file that is downloaded to the computer / smartphone / tablet user to access certain web pages to store and retrieve information about the navigation is made from that computer.
Technically , cookies are arbitrary pieces of data defined by the web server and sent to the browser . The browser returns to the server unchanged , reflecting a state ( memory of previous events) in the HTTP transactions that otherwise would be independent of the state.
Cookies specifications suggest that browsers should support a minimum number of cookies or a minimum amount of memory to store . Specifically , it is expected that a browser is capable of storing at least 300 cookies 4 kilobytes each, and at least 20 cookies per server or domain .
The server sets the cookie can specify a deletion date , in which case the cookie will be removed on that date. A shopping site might want to help potential customers remember the things he had in his shopping cart even if they close the browser without making a purchase and return later to avoid having to search for new products . In that case , the server would create cookie deletion date as desired by the designer of the website. If a deletion date is not set, the cookie is deleted when the user closes their browser. Therefore, set a date of deletion is a way to make the cookie survive across sessions. For this reason, dated erase cookies are called persistent.
