This article refers to the new EU regulations concerning Cookies.
A cookie is a piece of data stored by a website within a browser, and then subsequently sent back to the same website by the browser. For example, storing log in details or remembering basket content when leaving the website and returning later on. These are designed to help you quickly and easily navigate the internet.
Although cookies cannot carry viruses, and cannot install malware on the host computer, tracking cookies and especially third-party tracking cookies are commonly used as way to compile long-term records of individuals' browsing histories — a major privacy concern that has prompted European and US law makers to take action
Some third-party cookies are cookies being set with different domains from the one shown on the address bar.
For example: Suppose a user visits www.example1.com which sets a cookie with the domain ad.foxytracking.com. When the user later visits www.example2.com, another cookie is set with the domain ad.foxytracking.com. Eventually, both of these cookies will be sent to the advertiser when loading their ads or visiting their website. The advertiser can then use these cookies to build up a browsing history of the user across all the websites this advertiser has footprints on.
