Nginx reverse proxy redirect

[Dr_tux]

Hi guys,

I have a Nginx reverse proxy. How can I redirect it to the real server URL
when I download mp3 files in the reverse proxy.

For example:

normal reverse proxy request goes to backend node, but If the url contains
mp3, it redirects to another server.

Thanks.
