I use wordpress for my podcast. Every week I upload 2 mp3 files to the web, one to my hosting service and one to ourmedia.com, I always link to the mp3 on my hosting provider and after one month or so, I change the link to the ourmedia file.
I just noticed that the rss2 feed "remembers" all the links I've done to different mp3 files and sometimes it downloads the mp3 from my hosting provider.
How can I avoid this?
