Anybody thats done any development work in Flash knows how frustrating caching can be. With the introduction of external XML data this frustration only grows. So here's a technique that I use quite often to workaround this native behavior without creating a thousand incremental file names.
Using PHP, Javascript or the like, simply add a random number to the url string where you call your swf. Here's a couple examples..
PHP
fla/secParent.swf?noCache=<?php echo rand(0, 10000); ?>
