On 26th May 2012 a new EU Law came into legal use. A Cookie is also known as a web cookie, html cookie or even a browser cookie is a small bit of data or code that can be stored on a computer web browser or internet database. These cookies can be used or implemented in many forms of use such as tracking users for visiting websites, re-visits, analytics of who and where the visitors are from.
The internet and website tracking cookies and especially third-party tracking cookies are commonly used as ways to compile long-term records of traffic and visiting individuals' browsing histories — this is the major privacy concern that has prompted the EU and US law makers to take action and implement guidelines for the internet and website owners.
No, we didn't forget the Chocolate cookies but with a list of cookies as long as there are it's understandable why people are so confused with the Cookie Law.
The BBC technology website and the Information Commissioners Office (ICO) explain things in an even easier term with advice on the new "Cookie Regulations" download.
