Removing header through docker labels

Hi everyone,

the documentation says:

Please note that it is not possible to remove headers through the use of labels (Docker, Rancher, Marathon, ...) for now.

I just did it:

- traefik.http.middlewares.testheader.headers.customrequestheaders.Origin=

It is a bug that it should not work or is the documentation not up-to-date?

Best,
Andreas

Hello,

do you mean that - traefik.http.middlewares.testheader.headers.customrequestheaders.Origin= remove the header?

Yes, it does. It's not emptied, it's just gone (according to tcpdump):

Other things are different due to docker-compose up.
