Topic: mime type xspf+xml

[Neririn]

I hope this is easy and I am just not getting it...

I am trying to serve .xspf playlists from my SME 7.0 box.  The mime type should be application/xspf+xml.  I've tried putting addType application/xspf+xml in the /etc/mime.types using custom-templates, and I've also tried putting it in a .htaccess file for the specific document root.  

The problem I get is when I try to access the .xspf playlist from a flash mp3 player, or even just access it directly from a browser, I get application type unknown.

Am I missing something?  Can't 'new' mime types just be defined in such a manner?  Do I need to compile the support into apache?

PLEASE HELP!
