Can't use auth_patterns with --experimental_downloader_config

[calebzulawski]

Description of the bug:

I have a downloader config that looks something like:

rewrite https://company.com:8443/(.*) https://company.com/$1

and a rule that looks like:

http_archive(
    name = "archive",
    url = "https://company.com:8443/archive.tar.gz",
    auth_patterns = { "company.com": "Bearer <password>" },
)

Only some networks need the rewrite, otherwise I would just change the URL. With this configuration, the auth_patterns are never used despite pointing to the same host.

Which category does this issue belong to?

No response

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

You would need a remote archive that needs authentication, but I would think changing the url arbitrarily and using the downloader config would reproduce it.

This definitely looks like something worth fixing. However, due to limited capacity, we don't have time to work on it right now. PRs from the community are welcome!
