Bug 77349 – Track the NPN protocol version negotiated with the server

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit Misc.

[raman tenneti]

This is part of measuring effectiveness of SPDY; Track the protocol version (http/1.1, spdy/2 or spdy/2.1 or ...) which was negotiated with the server using TSL/NPN mechanism. chrome:loadtimes will display the protocol version that is negotiated.

Hi Darin,
  We wanted to add support in chrome:loadtimes to print the NPN protocol that was negotiated (servers could decide which SPDY protocol they would like to use - either SPDY/2 or SPDY/2.1. We would like to log the protocol server and client have negotiated). 

Would appreciate your comments.

thanks
raman

this field and the NpnNegotiated field don't really belong in webkit.  you are adding
this one here just as plumbing.  the same was true when NpnNegotiated was added.

since then, we have developed a way to attach opaque extra data to a WebURLRequest
(and underlying ResourceRequest).  can you use that instead?

see WebURLRequest::setExtraData.

On the chromium side, look at RenderViewImpl::willSendRequest to see where
setExtraData is called.

it would be great if you could move NpnNegotiated too! :-)

The above is awesome. Will make the above changes and will resubmit it for review.
