A cookie is a text file sent from a web server (for example, the website) to the user's internet browser, which automatically stores it on the user's computer and automatically sends it back to the server each time the website is accessed. Each cookie contains different data, such as, for example, the name of the server from which it originates, a numeric identifier, etc. Cookies can remain on the system during the login period (i.e. until the browser used to navigate the web is closed) or for longer periods and may contain a unique identifier. By default, almost all web browsers are set to automatically accept cookies. However, each web browser allows you to restrict and delete cookies. Please remember, however, that disabling or deleting cookies may prevent optimal use of certain areas of the site or compromise the use of services that require authentication.
