Save bandwidth on your hosted MP3's
Thanks to the Internet Archive's new FreeCache project, you can conserve your bandwidth when posting links to your MP3 or other media files.
Just stick the URL: http://freecache.org/
...in front of your own URL. Like this:
http://freecache.org/http://yourserver.com/yourfile.mp3 (don't click this -- it's just an example)
The system will locate another server that has already downloaded and cached the same content, saving your server a headache and speeding up the download for your listener.
