“Internet Cookies” (known as “browser cookie” or “HTTP cookie” or simply “cookie”) are small dimension files formed of letters and numbers that will be stored on the computer, mobile or other terminal equipment of a user of the Internet. The cookie is installed through the request of a web server of a browser (ex. Internet Explorer, Chrome) and is completely “passive” (does not contain software, viruses or spyware and cannot access the information stored on the hard disk of the user). A cookie is formed of 2 parts: name and content or value of the cookie. Moreover, the period of existence of a cookie is determined; technically, only the web server that sent the cookie can access it again from the moment in which a user returns on the website associated to that web server.
