I want to shorten the url displayed in the status bar when you hover the mouse over a link.

The only way I've been told to do this is <a href="http://www.LongURL.com/" onMouseOver="window.status='http://www.ShortenedURL.com'; return true;" onMouseOut="window.status=''; return true";>Link Description Here</a>

But it makes absolutely no difference in Firefox and the long url still shows up in the status bar, while in Internet Explorer nothing at all shows up in the status bar.

Is there a way of getting the shortened url to display in the status bar of most (if not all) browsers?

Thanks.
