HTTP2 HAR导出在Chrome中显示HTTP版本“未知”？

Question

I was looking at network requests from my Chrome Version 41.0.2272.104 (64-bit) and saw a curiosity with a request to Google Analytics' collection endpoint:

There are several headers I do not recognize: :authority: , :method: , :path: , :scheme:

:authority: seems to replace the Host header of HTTP 1.x, the :method: I'd expect to be an HTTP verb, not a header

A HAR export of Chrome reports the HTTP version as "Unknown" - see http://pastebin.com/1LjRVeHb

What's going on?

Answer 1

I just found the "funky" : prefixed headers in the HTTP 2 Spec as "Pseudo headers".

However seeing them in the HAR as "HTTP Version: Unknown" seems odd. Is there a Bug with chrome's own HAR export showing the request as HTTP Version Unknown? Could the "server" response header with "Golfe2" reveal any more information?
