How to avoid external js file being cached ?

Hi there,
Does anyone know a working tip to avoid an external js file being cached,
whathever the client cache policy is ?

Thanks in advance,

Try this,

<script>
var dt = (new Date()).getTime();
document.write( "<scr"+"ipt src='file.js?time="+dt+"'></scr"+"ipt>" );
</script>

Idea behind the code is to fool the browser with a different url every
time the page loads.
I have not tested, see if it works.
