Thanks for the PR @mgaligniana -- I think the HTTP_X_FORWARDED_HOST handling needs to be added manually on top of the vendored in code. As far as I can tell we also did that in the current version as the original upstream 1.0.1 version also doesn't contain it.

Ok, Seer 🎉 liked!

But codecov not, should I add new tests for the new vendor?

Edited: I think yes because Anton said:

Also make sure this code is tested to have a high test coverage. (maybe by vendoring in the related tests from Werkzeug?)

But do you think I should copy-paste the test from werkzeug to get_host for example?

Tests would be great. I think the one you linked would be good, plus something custom for the HTTP_X_FORWARDED_HOST stuff.

So adding that now we have

There we go!
