Hi

Sorry for the delay. Below is a simple class and html file that gives me
the error I described. You can set the url for the post to anything it
fails before the request is sent.

I hope this is enough info.

TestCase.class
-----------------------------------------
package junittests;

import java.net.URL;

import org.junit.Test;

import com.gargoylesoftware.htmlunit.HttpMethod;
import com.gargoylesoftware.htmlunit.WebRequestSettings;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

public class TestCase {

	@Test
	public void test() {
		try {
			WebRequestSettings reqSet = new WebRequestSettings(new URL(
					"http://localhost/test.html"), HttpMethod.POST);
			HtmlPage page = ReporterTestHelper.webClient.getPage(reqSet);
			Thread.sleep(5 * 1000);
			System.err.println(page.getWebResponse().getContentAsString());
		} catch (Exception e) {
			e.printStackTrace();
		}

	}

}

 function ajax(parArr, callback)        {
