Flash site won't refresh?

Hi.
I want my site to refresh every time I open it. I’ve been looking at the unique identifier script, but I can’t seem to understand where it goes. Is it in the HTML with the SWF or in the SWF itself?

I found this, can someone please explain how I use it:

*When you load a movie, variables, or a text, what you load is put in the cache of your computer by your browser. This can cause problems because if you load files, chances are that you are going to update them quite often, but Flash will look for the files in the cache, that is to say the old ones.

The solution is to load your files with a unique identifier. Example:

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

This works also with LoadVariables, LoadMovieNum and LoadVariablesNum.*
