Cookies are small text strings that the sites visited by the user send to his terminal (usually the browser), where they are stored before being re-transmitted to the same sites at the next visit by the same user. Cookies are stored, according to user preferences, by the single browser on the specific device used (computer, tablet, smartphone).


Based on their characteristics and use, cookies can be divided into different categories:

Strictly necessary cookies

These are cookies that are essential to manage login and access to the site’s reserved functions, typically for web editors to update pages. The duration of these cookies is strictly limited to the work session (when the browser is closed they are deleted). Their deactivation compromises the use of the services accessible from the login. The public part of the sites, on the other hand, remains normally usable.

Technical cookies (analysis and performance)

These cookies are used to collect and analyze traffic and use of the site anonymously. These cookies, even without identifying the user, allow for example to detect if the same user returns to connect at different times. They also allow you to monitor the system and improve its performance and usability. In some pages of the site they can memorize the user’s preferences regarding the font size and the preferred display mode (graphic, high contrast or textual) for the purpose of accessibility of the contents. The deactivation of these cookies can be performed without any loss of functionality.

Profiling cookies

These are permanent cookies used to identify (anonymously or not) user preferences and improve their browsing experience.


Some cookies (session cookies) remain active only until the browser is closed or the logout command is executed. Other cookies “survive” when the browser is closed and are also available in subsequent visits by the user. These cookies are called persistent and their duration is set by the server at the time of their creation. Browsing through the pages of the site , you can interact with sites managed by third parties that can create or modify persistent and profiling cookies. The temporal conservation of each individual cookie is visible in the “cookie list” table. 


The user can decide whether or not to accept cookies using the settings on his browser. The total or partial disabling of cookies could compromise the use of the site features, but does not prevent navigation. The setting can be defined specifically for different websites and web applications. The following web resources illustrate how to proceed for each of the main browsers: Chrome , Firefox , Internet Explorer , Opera , Safari .
