Saving the result of a WWW query?

Hi,

I'm making an app with a soundtrack that is stored on a server, and updated music is downloaded on startup (I'm using WWW to download mp3s from the server). Realising that this could be a big download to do every time the game boots, I was thinking of storing the downloads and reading the stored version unless the user specifically opts to re-download them. But I couldn't find a way of saving the results of a download from a WWW call, or even a way to find out where they are saved.

Is there a way of saving downloaded data from WWW, or is it saved in a local path somewhere that I can just read via a script?
