I use an img tag to pull something that I know exists from my target, and JavaScript to pull something from my own machine if the img from the target fails. Maybe you could build from this:

<script type="text/javascript">
 Now=new Date();
 Out ='<img src="http://target.com/green.gif';
 Out+='?'+Now*1;
 Out+='" onerror="this.src=\'red.gif\'"/>\n';
 document.write(Out);
</script>
