Cache-problem

on the button:

on (release) {
	mySound.loadSound("../music/01.mp3", true);
}

on the frame

mySound = new Sound();

Here’s my code. The problem is that the mp3 is stuck in IE’s cache. How do I get around this?

And why is it that there is thousands of flash-tutorials but almost none of them gives you a code that allready avoids the caching-problems?
