How does this command line flag interact with the --use-spdy flags? For example,
how does it interact with flow control?

If --use-sdy=off, then enable-spdy3 is ignored.

Currently HttpStreamFactory::SetNextProtos is accumulating all next_protos. If
flow control is enabled and enable-spdy3 is enabled, then chrome supports
http/1.1, spdy/2, spdy/2.1 and spdy/3.

Would appreciate your opinion on if we should do something different.

thanks much.

What about --use-spdy=v3? or --use-spdy=flow-control?
