<p>This tests that onload events can be attached to link elements with rel=prefetch. Since prefetch links are just there as a performance optimization, the onload event is their only programatic side-effect.</p>
<p>If it works you should see a message below saying the test has passed.</p>
<link href="prefetch.link" rel="prefetch" onload="done()" >
<hr>
