DELETE on Registry with Basic Auth not working

[mabaum]

Hi, I use this docker registry UI and I have an issue...

Bug description

I have set up a Registry which requires Basic Auth. The Registry lists all Images and Tags correctly.
When i Click on "Delete" within the UI an error "Access on registry response was blocked. Try adding the header Access-Control-Expose-Headers: Docker-Content-Digest to your proxy or registry: https://docs.docker.com/registry/configuration/#http" is displayed but on the Console u can see that there is an 401 delivered back to the UI from the registry

How to Reproduce

1. Log into a Registry secured by Basic Auth
2. Click on 'Delete' on any Image
3. Error is displayed

Expected behavior

Successful delete (maybe a Basic auth Dialog from Browser before)

Hi

is your issue related to #104 ? The registry is buggy, it returns 401 status codes on OPTIONS for DELETE requests and that's not how to do it... The full explanation here.

yes was #104

https://enable-cors.org/server_nginx.html did the part with the OPTIONS header within my nginx - config :)
