How cookies are used

What is cookies?

Cookies are small text files, which enhance the user experience on a web site by allowing the system to recognise returning visitors, etc. Cookies are sent back and forth between your browser and a web server and contain information about e.g.:

  • user preferences
  • if a user is logged in
  • how the website is used.

A cookie is a passive file and can not spread computer viruses or other malicious programs. Often cookies help analyze how the website is used, and the web editor can improve the user experience. In several cases, cookies may be necessary to provide a service. Cookies are mostly erased automatically from the browser when it is closed (so-called session cookies). Cookies can also be set with an expiration time so that data exists for a shorter or longer period (persistent cookies). Persistent cookies are usually stored on the hard disk. Moreover distinction is usually drawn between first-party cookies and third party cookies. First-party cookies are set by the page the user is visiting. Third-party cookies are set by a third party that has elements embedded on the page the user visits. Third-party cookies are set among other by web analytics programs.
