Hi,
I am using HttpClient 3.0 and have a problem with preemptive
authentication and redirects.
The scenario is as follows:
1. I create a GetMethod with a certain URI, lets say www.foo.com which
redirects to bar.foo.com
that requires authentication.
2. I lookup a registry with stored credentials for this URI and find
Username + Password
3. I call HttpClient.getParams().setAuthenticationPreemptive(true);
4. I create AuthScope and Credentials, asking the GetMethod for Host,
Port and Realm. For Host
I am getting "www.foo.com".
5. I call HttpClient.getState().setCredentials(authScope, userPwCreds);
6. I call getMethod.setDoAuthentication(true);
Now, I execute the GetMethod and it gets redirected to "bar.foo.com".
Thereby the AuthScope
I created preemptively with "www.foo.com" is no longer valid. I get an
401 error, although
the credentials are correct, just the host is not.
Is there a workaround for avoiding this problem? I tried to supply
ANY_HOST as value for
the AuthScope but get the exception that NULL is not allowed (though the
API tells me
that I can supply ANY_HOST if I want to).
Thanks for helping,
Ben
