There is no application layer transfer protocol inherent in websockets.
Requesting a resource does not have any inherent meaning other than that
you are opening a "channel" onto /image/kitten.png. Whoever receives that
request is free to respond to that however he likes. You would need to
introduce an application layer content protocol on top of websockets, and
introduce a default websocket server framework capable of understanding
such content requests. You're not just extending lazy reading to
websockets. You're putting the burden on yourself to also specify a
completely new standard application layer protocol for transfer and range
and acquisition of resources over websocket channels.
