I don't know what component does it belong to.
I have jenkins behind a https gateway. Gateway gets request at 443 and forwards to jenkins running at 8080.
It works fine for many urls but when I click on any plugin/job url which doesn't end in `/` then jenkins redirects to an http url with a `/` at the end, which breaks because there's no http.
I already have the https url configured in ConfigureSystem settings, yet jenkins keep redirecting to a http url.
It's probably duplicate of https://issues.jenkins-ci.org/browse/JENKINS-10675
