    " a web server can store information about you and your browsing activities"
    " on your machine for later use. You might consider this an invasion of"
    " privacy. <p> However, cookies are useful in certain situations. For example, they"
    " are often used by Internet shops, so you can 'put things into a shopping basket'."
    " Some sites require you have a browser that supports cookies. <p>"
    " Because most people want a compromise between privacy and the benefits cookies offer,"
    " KDE offers you the ability to customize the way it handles cookies. So you might want"
    " to set KDE's default policy to ask you whenever a server wants to set a cookie,"
    " allowing you to decide. For your favorite shopping web sites that you trust, you might"
    " want to set the policy to accept, then you can access the web sites without being prompted"
    " everytime KDE receives a cookie." );
