Cannot strip QS in rewrite

[aquilinux]

Hi Maxim, thanks for the rewrite_log hint.
Actually it does rewrite as expected:

2019/06/21 12:35:37 [notice] 7495#7495: *4693835 "(?i)^/ambassadors$"
> matches "/ambassadors", client: 1.1.1.1, server: www.example.co.uk,
> request: "GET /ambassadors?test=1 HTTP/1.1", host: "www.example.co.uk"
> 2019/06/21 12:35:37 [notice] 7495#7495: *4693835 rewritten redirect: "

> /ambassadors?test=1 HTTP/1.1", host: "www.example.co.uk"


but i still get the response as above.
So i suspect the culprit may be varnish, saving the QS in be.req and
re-adding the QS in be.resp .
I see no other explanation.

Thanks!
