hi,  
i have tried following the kirupa tutorial on solving cache problems, but it doesn’t seem to work.  
I have a main html page with a flash button on it. Once you click on it, it opens a pop up window with a swf in it. What i am trying to do is to force tha pop up window to reload everytime poeple come back on it, as i have a preloader animation, etc… but it keeps on loading the swf stored on the cache.

Should the code be:

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

content being the swf loaded in the pop up?

many thx
