I have a working ping-over-http mobile browser app at alt.reed.com. feel free
to try it and look at the underlying packet stream with wireshark. I did a
prototype of a RRUL test using Web sockets and a modified nginx websocket
module as a server that could be commanded to generate precise traffic and
server end measurements ... it showed this can work up to a few 10 s of Mb/s.
It's slightly tricky and requires a good understanding of the Web sockets
protocol stack.
