Cookies are small text files that the visited sites send to the terminal of the user, where they are stored, before being re-transmitted to the same sites on your next visit. Cookies of the c.d. "Third parties" are, however, set by a website other than the one the user is visiting. This is because on each site there may be elements (images, maps, sounds, specific links to web pages of other domains, etc.) that reside on servers other than the site visited.
Types of Cookie
According to cookie characteristics and use, we can identify various categories:
1. Technical Cookies. These cookies are used solely for the purpose of "transmitting information over an electronic communications network, or when strictly necessary to the supplier of an internet-based service who has been explicitly asked by a subscriber or user to provide that particular service" (cf. Art. 122, Para. 1, Italian Civil Code). These cookies are not used for any other purpose and are normally directly installed by the owner or the manager of the website. They can be subdivided into: navigation or session cookies, which ensure the normal navigation and use of the website; analytics cookies, classed as technical cookies when used directly by the site manager to collect information, in aggregate form, on the number of users and on how users actually visit the site; functionality cookies, which according to select criteria improve the user's navigation experience. Installation of these cookies does not require prior user consent, though, in accordance with Art. 13 of the Italian Civil Code, the site, where these are the only such devices used, must provide notice of their use in the manner its managers see fit.
2. Targeting Cookies. These cookies aim to create user associated profiles and are used in the sending of advertising messages matched to a user's net navigation preferences.
Duration of Cookies
Some cookies (session cookies) deactivate at browser closure or at logout. Other cookies "survive" browser closure and are available during the following visits by the user. These cookies are called persistent cookies and their lifespan is fixed by the server at the moment of their creation. In some cases, an expiry date is fixed, in others their duration is unlimited.
Cookie Management Most browsers automatically accept cookies, but users can usually change their browser settings to disable this feature. The "Help" section of the toolbar in most browsers explains how to avoid receiving cookies, web beacons and other tracking technologies, how to get notification from the browser of activating these technologies or how to disable them completely. Disabling cookies may limit the possibility of using the related site and prevent users from fully benefiting from the features and services on the site.
