You might create an object, though, that is both credentials provider and
auth cache.
This is probably the only solution.
But my example still stands, I think.
A credentials providers serves up and caches
a set of credentials.
During the lifetime of that provider, the credentials
become out of date. There is no way (other than your proposal
to combine AuthCache and credentialsprovider) to get that bad
set of credentials out of the providers cache. It will be
repeatedly invoked and will keep serving up the same bad credentials.
Naively, I would have thought this was a problem. In any case, I will
use your proposed solution for now.

Actually it is AuthCache [1].
That does not seem correct to me. I looked
at AuthCache (BasicAuthCache actually) and it never
even references a credentials provider. It is
caching a map of HttpHost->AuthScheme.
Why should it? This is what credentials provider is for. The cache
contains auth challenges HttpClient can successfully respond to, not
user credentials.
So I looked ocurrences of AuthProtocolState.FAILURE
and while the AuthCache is invalidated, nowhere that I
can find is any corresponding credentials provider
be notified.
I am not entirely sure why it should be notified. There is no definitive
way of telling why a particular auth response got rejected (other than
parsing the response body).
You might create an object, tough, that is both credentials provider and
auth cache.
