Hello, I facing strange problem with HttpClient
For some reason if there are more than 1 Location header in response, all
headers are collected into single string, for instance -
/madeline/?GCID=C1000x047&AID=10280172&PID=1453275, /madeline
I used this test:
import junit.framework.Assert;
import junit.framework.TestCase;
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.cookie.CookiePolicy;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.params.HttpClientParams;
import org.apache.commons.httpclient.params.HttpMethodParams;
import java.io.IOException;
public class HTTPClientTest extends TestCase {
HttpClient client;
HttpMethod method;
protected void setUp() throws Exception {
client = new HttpClient();
String url =
"http://www.allaboardtoys.com/madeline/default.asp?GCID=C1000x047&AID=10280172&PID=1453275";;
URI uri = new URI(url, url.indexOf('%') != -1);
method = new GetMethod();
method.setURI(uri);
HttpMethodParams params = method.getParams();
params.setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
params.setParameter(HttpClientParams.USER_AGENT, "Mozilla/4.0"
+ "(compatible; MSIE 6.0; Windows NT 5.1;)");
method.setFollowRedirects(true);
}
public void testResultcode() {
try {
client.executeMethod(method);
Assert.assertEquals(HttpStatus.SC_OK, method.getStatusCode());
} catch (HttpException e) {
e.printStackTrace(System.out);
} catch (IOException e) {
e.printStackTrace(System.out);
}
}
}
With tcpflow i found:
request was

As you can see, instead of http://www.allaboardtoys.com/madeline HttpClient
used
/madeline/?GCID=C1000x047&AID=10280172&PID=1453275, /madeline
which is wrong.
I tried to handle redirects manually, but contents of header "location" are
http://www.allaboardtoys.com/madeline/?GCID=C1000x047&AID=10280172&PID=1453275,
/madeline
Is it correct to split it by comma or I can get list of headers manually
somehow?
