html5 video: http range request spec??

i am implementing a java servlet, serving html5 videos.
implementing the range protocol for safari is very difficult.

1) missing tool support
safaris built in tools (resource view) shows all http requests (request and response headers) for all kind of files like images etc, but not for html5 video!! this is very bad. on firefox there is firebug which shows all requests/responses and allowed me to find the correct protocol and implement it.

2) missing specification
searching the web for the required http range protocol did not lead to an answer.
the first request of the video element has following properties:
range: bytes=0-1
connection: close
user-agent: Apple Mac OS X v10.6.5 CoreMedia v1.0.0.10H574
accept: /
accept-encoding: identity
why close and not keep alive? i correctly serve what is requested - 1 byte (tried all means).
but there never comes a second request...

hope anyone has an answer.
thanks!
