[jira] [Commented] (HTTPCLIENT-1129) Redirect and Kerberos
authentication in conflict
[ https://issues.apache.org/jira/browse/HTTPCLIENT-1129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13121983#comment-13121983 ]
Oleg Kalnichevski commented on HTTPCLIENT-1129:
-----------------------------------------------

One thing I do not understand. Why does HttpClient need to re-authenticate on redirect in the first place? This makes no sense as the connection has been already authenticated and HttpClient re-uses the same connection for redirected request. Am I missing something?

> Project: HttpComponents HttpClient

> 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.
