By setting realm as null, the pre-emptive authentication worked! But, it
sends a Basic Authorization header even if the URL is protected by
Digest! For Digest it is still making 2 trips in order to authenticate.
Which is fine for the first request, but it repeats the same thing for
the second request as well. Is there a way to tell the state, method or
client what kind of scheme is desired for pre-emptive authentication.
Sorry, no logs here as log did not work.

Zulfi,
Try setting both realm & host to null. That should do the trick
HttpClient hc = new HttpClient();
HttpState state = hc.getState();
state.setAuthenticationPreemptive(true);
// Set default credentials (realm & host are null)
state.setCredentials(null, null,
new UsernamePasswordCredentials("zulfi", "zulfi"));
Folks,
The present convention for setting a default set of credentials is
utterly confusing and needs to be redesigned in 2.1. I believe we should
be using HttpState#setCredentials(HttpAuthRealm, Credentials) instead of
HttpState#setCredentials(String, String, Credentials). We should also
provide a static final class to represent the default set of
credentials:
public static final HttpAuthRealm DEFAULT_AUTH_CREDENTIALS = new
HttpAuthRealm(null, null);
The end user code might look similar to that below
state.setCredentials(DEFAULT_AUTH_CREDENTIALS,
new UsernamePasswordCredentials("zulfi", "zulfi"));
Cheers
Oleg

Subject: preemptive
Tried to use the Preemptive Authentication feature. Could not get it
to
work. I used the HttpState.setAuthenticationPreemptive(true); to set
the
preemptive authentication ON. It still send the first request without
the Authorization header. Code sample is below. Would like to know,
how
to set up the Pre-emptive Authentication.
package test;
import java.io.*;
import java.net.URL;
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
import org.apache.commons.httpclient.auth.*;
import org.apache.commons.httpclient.util.*;
public class JCTest {
public static void main(String[] args) throws Exception {
test0();
test0();
return;
}
public static void test0() throws Exception {
System.out.println("running test0");
String urlstr = "http://localhost:9999/services1/test";;
URL url = new URL(urlstr);
HttpClient hc = new HttpClient();
HttpState state = hc.getState();
state.setAuthenticationPreemptive(true);
state.setCredentials("", url.getHost(),
new UsernamePasswordCredentials("zulfi", "zulfi"));
PostMethod post = new PostMethod(urlstr);
post.setDoAuthentication(true);
post.addRequestHeader("Connection", "Keep-Alive");
post.addRequestHeader("Content-Length", ""+msg.length());
post.addRequestHeader("Content-Type", "text/xml;
charset=utf-8");
InputStream reqis = new ByteArrayInputStream(msg.getBytes());
post.setRequestBody(reqis);
HostConfiguration hconfig = new HostConfiguration();
hconfig.setHost(new URI(urlstr));
hc.executeMethod(hconfig, post);
System.out.println(post.getResponseBodyAsString());
System.out.println();
}
private static String msg = "Text Message";
}
Thanks.
