A cookie is a small text file that is stored in the website visitor’s computer. Cookies are regularly used in order to improve a website for the user. There are two types of cookies: One type saves a file that is kept on the visitor’s computer. That kind of cookie can, for instance, be used to configure a website based on the choices the visitor makes. The other type is a “session cookie”. These cookies are temporarily stored during a visit to the site, and are removed as soon as the user closes the browser. If you do not want to accept cookies you can turn them off in the browser settings. However, some website functions may not work satisfactory if you turn cookies of completely. You can also configure your browser to warn you every time a website tries to create a cookie on your computer.
