preemptive

[Zulfi Umrani]

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.
