Hi there, I'm following your digest Authentication Sample to try access an API that has this kind of security, the problem is that it is always returning me Authentication error: basic authorization challenge expected, but not found.

Basically my code is something like this:

    public static void get(String url, RequestParams params, AsyncHttpResponseHandler handler){
        AsyncHttpClient client = new AsyncHttpClient();
        client.setAuthenticationPreemptive(true);
        client.setCredentials(AuthScope.ANY,new UsernamePasswordCredentials("user","pass."));
        client.get(getAbsoluteUrl(url), params, handler);

    } 

Also I downloaded your project from here, and tried to run your digest auth example (DigestAuthSample.java) and it always return Return Status Code 401
org.apache.http.client.HttpResponseException: Unauthorized at ..... (it goes on)
and it continues.

What's the correct way to successfully connect to a digest auth protected API?
