In computer science HTTP cookies (more commonly referred to as Web cookies, tracking cookies or just cookies) are lines of text that are used to perform automatic authentication, session tracking and storage of specific information about users that take place on the server. For example, favourite websites or the content of their "shopping carts" in the event of purchases.
In detail, therefore, they are text strings of small size, sent by a server to a web client (usually a browser) and then sent back by the web client to the server (unchanged) every time the user accesses the same portion of the same web domain.
Each domain or its portion that is visited with the browser may set cookies. Since a typical Web page, such as that of an online newspaper, contains objects that originate from many different domains and each of them can set cookies, having several hundreds of cookies in your browser is quite normal.
Since they can be used to monitor Web browsing, cookies are the subject of discussions concerning the right to privacy. Many countries and organizations, including the United States and the European Union, have legislated on the matter. Cookies have also been criticized because they are not always able to identify the user accurately and also because they can potentially be subject to cyber attacks. Some alternatives to cookies do exist, but all of them, along with some advantages, have drawbacks.
Cookies are often wrongly considered as actual programs and this generates erroneous beliefs. In fact they are simple pieces of data, incapable, alone, of taking any action on a computer. In particular they can be neither spyware nor viruses. In spite of this, cookies from certain sites are classified as spyware by many anti-spyware products because they make it possible to identify the user. Modern browsers allow users to decide whether to accept cookies or not, but any refusal makes some objects unusable. For example, "shopping carts" implemented using cookies do not work in case of refusal.
