Re: getting through a proxy server

Michael Becke Fri, 08 Oct 2004 11:21:29 -0700

Hi Madeleine,

The first request fails because the credentials are not sent on the first method execution. This is for two reasons. One, because the proxy credentials have been specified with a particular realm. HttpClient does not know that a URL is protected by a particular realm until is tries and fails. Also, HttpClient by default does not include credentials in requests except when challenged or when preemptive authentication has been turned on. You should be able to fix this problem by doing the following:

// use a null realm
client.getState().setProxyCredentials(null, "cache.ru.ac.za", creds);
// enable preemptive authentication
client.getState().setAuthenticationPreemptive(true);

Hi.
Thanks for all the suggestions. I tried replacing client.getHostConfiguration()..with method.getHostConfiguration butit didn't seem to make any difference. I changed "method" back to "client" and retried and for the second attempt it did authenticate me - but not for the first. Initially I had this: retryhandler.setRetryCount(3); but then I changed the "3" to "1". Again the first try was refused but the second got through.

What I would like to understand is which host configuration is being accessed by client.getHostConfiguration().., the proxy host, the ultimate destination or me??

I was using a logger - and I'm appending the output with the retry at "1" (not that it's any shorter!). Is there something in the order of the code that causes a refusal the first time around that gets fixed the second time? Currently my code (comments stripped out) looks like this:
public class MyHttpClient {
 private static String url = "http://www.uct.ac.za/";;
public static void main(String[] args) { HttpClient client = new HttpClient(); GetMethod method = new GetMethod(url); client.getHostConfiguration().setProxy("XXXX", XXXX); Credentials creds = new UsernamePasswordCredentials("XXXX", "XXXX"); client.getState().setProxyCredentials("XXXX", "cache.ru.ac.za", creds); Logger logger = Logger.getLogger(MyHttpClient.class); BasicConfigurator.configure(); logger.info("Entering application."); DefaultMethodRetryHandler retryhandler = new DefaultMethodRetryHandler(); retryhandler.setRequestSentRetryEnabled(false); retryhandler.setRetryCount(1); method.setMethodRetryHandler(retryhandler);
   try {
     int statusCode = client.executeMethod(method);
     if (statusCode != HttpStatus.SC_OK) {
       System.err.println("Method failed: " + method.getStatusLine());
     }
     byte[] responseBody = method.getResponseBody();
     System.out.println(new String(responseBody));
   } catch (IOException e) {
     System.err.println("Failed to download file.");
     e.printStackTrace();
   } finally {
     method.releaseConnection();
   }
 }
}
The error log follows.
Thanks so much.
