The web server will only return content if the pages have changed since the last time visited. If content is returned by the web server, the browser can cache this data and inform the user that new content is available by changing the color of the corresponding hyperlink on the current page. As an added feature, the user can specify which sites he/she wishes to receive update notification on through any browser implemented mechanism.

     If a user visits a page that they wish to receive update notification on, the browser already parses the hyperlinks and changes their color depending on whether or not they have already been visited.

If the server responds with a page, the corresponding link will change to some alternate color, flash or otherwise unobtrusively and visually cue the user that the link is associated with new content.
