I have some mp3 files hosted on a server on a shared hosting account and I have trouble submitting my podcast feed to the iTunes store. Apple rejects the feed, because they say my episode files are hosted on a server that do not support byte ranges - similar to this case.
I have contacted my service provider and they claim that the server does support byte ranges and inspecting the http header of a hosted episode looks like they are right:
Is there any method that can verify this beyond doubt?
