Preloading external swfs in background

Is there a way to tell flash to preload a number of swfs in the background (meaning no visual cue to the end user that this is happening), while the current movie is playing?

The idea is when the user clicks on a button to move to another area, that swf has already been preloaded in to memory or cache and loads instantly.

Or is there a better way to do this? Any help? :thumb:
