I want all mp3 files residing on my server to have "-xxx" added at the end of the filename when a user downloads them. Example:
file on the server: file.mp3
when user downloads: file-xxx.mp3
I've googled something that is pretty close to what I want:
As I don't want to be limited to any particular folder, and would like to have all .mp3's renamed on the fly, I've tried this:
RewriteEngine on
RewriteBase /
RewriteRule ([^.]+)-by-domain\.mp3$ $1.mp3 [L]but for some reason I can't get it to work, files don't get renamed.
Any help would be appreciated. Thanks!

The following worked when tested on my server
RewriteEngine on RewriteBase / RewriteRule ^/(.*)-([0-9]+).mp3 /$1.mp3
It works as follows - The RewriteRule is broken up into 4 parts,
- the prefix including the path and first part of the name of the file
- the "-"
- the numbers in the file
- the end part of the file (.mp3)
The script takes only the prefix from the original file - the part ^/(.*) and then rebuilds this into a new url (the $1 contains the part between the brackets in the part above).
The ([0-9]+) detects the unique number, so if you are wanting to do something more fancy later on you could write (for example) a PHP script which allows the user to download the file, and logs information about it by changing the rewrite rule to
RewriteRule ^/(.*)-([0-9]+).mp3 /path/process.php?mp3=$1&userid=$2
(You would need to write the php script as well of-course, but the example above shows the logic as to how the rewrite rule processes the URL into parts.)
