Test with and without HTTP/2

[nilskuhn]

Hi there,

I want to test a site capable of HTTP/2 with HTTP/2 and without (HTTP 1.1) to see the differences in performance, session handling and so on.

I try to disable HTTP/2 via setting a firefox preference in test script:

Code:

firefoxPref    network.http.spdy.enabled.http2    false
navigate    https://www.cloudflare.com

Resulting waterfalls look strange somehow:

cloudflare - first request isn't included in waterfall:

google - no request in waterfall at all:
http://www.webpagetest.org/result/160114_7A_M43/

twitter - same as with cloudflare, first request not in waterfall:
http://www.webpagetest.org/result/160114...1/details/

Any ideas?

Regards, Nils
