Many web sites need to know that you are returning to a web site that you’ve visited before. For example, if you tick ‘remember me’, then they need to remember you. The catch is that they need a way of remembering you.
The way they do that is by placing a tiny file in a special browser folder called a cookie. All this file has is the address of the web page you visited, a unique identifier (eg SHDJEWK) and an expiry date.
Whenever you visit a web page, it checks to see if you’ve been there before, and if you have, it can remember you.
EU law means that web sites have to ask permission and we have to accept each one manually. We cannot automate the process.
