Tests contain requests with User-Agent Microsoft-CryptoAPI

[IngoSteinke]

Hello all,

eventually some web page tests contain requests with
User-Agent: Microsoft-CryptoAPI/6.1
Host: gm.symcd.com

even though the tests are run with user agent Chrome and the original webpage does not contain any links to the aforementioned host.

Example: https://www.webpagetest.org/result/17042...view_step1
Request #2

Re-running the same tests usually results in a run without any of those requests.

This happens on http://www.webpagetest.org as well as on our local WPT installation.
I suspect Microsoft Windows Update agent to be the culprit.

These requests should not happen during a WPT test run.

Best regards,
Ingo Steinke
