always-auth for uplinks

[sergeimonakhov]

Is your feature request related to a problem?
Hi, I have 2 verdaccio servers and I wanted to proxy (add to uplinks) from one to the other, but since $authenticated is used for packages access, the request must contain authentication headers, but this is not the case. I get package.json, but download .tgz responsed 401 error

Describe the solution you'd like
Add always-auth: true/false key to uplinks config

Describe alternatives you've considered

Additional context

Hi, I'm experiencing the same issue with an authenticated uplink. The server successfully gets the package metadata, but the subsequent request for the tarball returns a 401. @sergeimonakhov did you ever find a way around this?
