Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

Ran `git push` to a remote whose URL 301-redirects to a new path before the server responds 401 with a WWW-Authenticate header.

What did you expect to happen? (Expected behavior)

wwwauth[] to be passed to my credential helper, as it is when pushing to the same server without a redirect.

What happened instead? (Actual behavior)

wwwauth[] was empty, so the helper couldn't detect the auth scheme.

What's different between what you expected and what actually happened?

The redirect causes wwwauth[] to be dropped

Anything else you want to add:

The credential helper in context is https://github.com/hickford/git-credential-oauth The server is a self hosted forgejo https://forgejo.org/
