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.
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
cookies are cookies being set with different domains from the one shown on the
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.
