media type audio/x-ogg or application/x-ogg should be added to Apache mime.types
Hi, I recommend the designers of Ogg vorbis decide on a media/mime type for
Ogg/Vorbis and submit it for inclusion to the Apache group. I suggest either
1) audio/x-ogg
2) application/x-ogg
With the media-type available, one can then utilise Apaches mod_expires module
to generate cache-friendly headers for ogg file which speeds up serving ogg
streams to people behind ISP proxy caches

This mechanism is explained in depth at
