The problem is the server isn't required to indicate supporting range even
if it actually does. (Apple's trailers servers if i remember correctly).

The spec doesn't mandate that the server set's the Accepts... header. (and
even if it does and i've missed it, alot of servers don't, but do support
seeks)
