> We are using the HttpClient to connect to a Website that uses Kerberos-Authentication.
> Beware this trigger word: Kerberos! I think this is *not* the problem, but please read
on.
> Here is the sequence of events:
> Client: GET /
> Server: Unauthorized.
> Client: GET / and includes authentication.
> Server: 302 to /something on the same host (this shows that in principle authentication
works)
> Client: GET /something,  does not include authentication
> Server: Unauthorized
> Client quits with 401-Unauthorized.
> I would have expected one of the following instead:
> 1) Client immediately sends authorization information with the redirected GET /something
> 2) Client re-requests the /something with authorization after 401-Unauthorized.
> We could get around the problem by setting the ConnectionReuseStrategy to a constant
false.
> It would be great if someone could tell me if HttpClient works as expected or whether
there is a bug or misconfiguration lurking.
> Thanks,
> Harald.
