So it seems I was able to resolve the issue. While the documentation seems very sparse, what helped me was a hint from the mailing list archives towards the example ClientPreemptiveBasicAuthentication.java class.

--------------------------------------
This code should work with all version of HttpClient 4.x. However, as of
version 4.1 the same can be done in a much simpler way by pre-populating
the auth cache:

Hope this helps

Subject: Preemtive Authentication for Artifactory

Hello there.

Trying to fire REST api commands to JFrog Artifactory, I am successful related to upload and delete.
Now I want to implement copy and move operations but seem to get "409 Conflict" or "405 Method not allowed" responses, although they might stem from the user not being authorized.

Ha, the user! HttpClient 4.5.3 does not even feel challenged and thus never sends the credentials. On copy and delete operations I traced that the server responds with a 403 which triggers HttpClient to resend the request including credentials.

How can I have the credentials sent in the first request anyway? The example at
http://hc.apache.org/httpcomponents-client-4.5.x/tutorial/html/authentication.html#d5e717
does not work for me. But then I am using POST requests...
