Hi,

Thanks for your contribution.

Can you update the tests reflecting your modification (in core/tests/documents/test_api_documents_media_auth.py).

Also, we only accept signed commits and your commit syntax does not follow our contributing guide. Can you take a look at it please ? (see CONTRIBUTING.md)

Thanks

@centerionware Thank you for your issue / pull request. I was able to make docs work with traefik.
I can tackle the tests if you do not currently have time !

If you want to take it over please be my guest. I don't have the time myself. It's such a small change, only spent like an hour doing the background research and testing to make sure it works. would probably be a good idea to do the tests, actually sign the commits (something I'm just not used to and it's such a weird requirement), and add the middleware parts to documentation in tree. if I can somehow 'sign' the past commits i will if that would make things easier, but frankly if you just want to copy and paste the changes to a new tree i really couldn't care less. It's not like it's a fancy new algorithm that revolutionizes the flow of streamlining the process of other random silicon valley market jargon.
