Stop Browsing Caching Data

I was reading this article: http://www.flashguru.co.uk/000023.php

But it does not explain where do use or put this variable:

unique=new Date().getTime() //will always be unique
this.loadVariables(“http://www.flashguru.co.uk/myscript.php?unique=”+unique);

Please advise!

Cheers,

Daniel
