European cookie law set to come into force

  • Thousands of European websites are likely to be in breach of a law that dictates what information they can log about visitors.

    European laws that define what sites can record in text files called cookies came into force on May 26.

    Cookies are primarily used to customize what repeat visitors see on a site, and by advertisers to track online users.

    The regulations state websites must get informed consent from users before they record any information in the cookies they store on visitors' computers.

    For websites that have complied with the law, getting consent has involved a pop-up box that details the changes. Users are then asked to click to allow having information recorded or told what will happen if they refuse.
