enable debug, validate request header fields.

just in case of multiple dns entries, make sure same ip address is connected to.

command line curl(*) range seems to work:
curl -v -r 1-10 http://cache1.tinyvid.net/otaku/3237ep5-Dragon_Ball_Z.mp4
curl -v -r 54513380- http://cache1.tinyvid.net/otaku/3237ep5-Dragon_Ball_Z.mp4

thus, check if the request header fields ultimately generated by your
programs are any different than command line tool

(*) curl 7.30.0 (x86_64-apple-darwin13.0) libcurl/7.30.0
SecureTransport zlib/1.2.5
