Refreshing flash

Kirupa’s got this code that’s supposed to fix flash so that it can keep up with new revisions (ie. when I change something I can go and see it has been changed, instead of seeing something that has been cached)…

myIdentifier=Math.round(Math.random()*10000);
loadMovie(“myAnim.swf?uniq=”+myIdentifier,1);

Can someone please explain how I can use it. Thanx.
