To do this insert this in the web page:
<a onMouseOver="window.status='http://fakeurl.com'; return true" onMouseOut="window.status='Done';" href="http://realurl.com"> Link </a>
It's important to place onMouseOut function as users will be curious when the find the 'destination' url stays there.
Other users will have different browsers [ other than Internet Explorer ] which may not say Done when a page has loaded but 89% of users do. Because of this 11% of your users may begin to get suspicious. The message is it's not full-proof.
