External mp3... again

well, I searched the forum for about half an hour and couldn’t get a decent answer to my problem:

I currently work on a game and decided to load an external mp3, like this:


Music = new Sound():
Music.loadSound("my_song.mp3", false);
Music.start();

This works totally fine on my local machine, and also on my server if the .swf the first time I view it. But apparently the browser caches the .swf and plays it from a local folder - thus, the mp3 fails to load. Has anyone an suggestions? I tried using the absolute URL (didn’t work), but as people might download the swf und put it up elsewhere that would mean the mp3 still would be loaded from my site… which I really want to avoid.

Any ideas?
