I'm a new user of Http Client 4.0 (beta 2) and I'm struggling with BASIC
authentication. I'm attempting to follow the authentication sample
using (simply):
httpclient.getCredentialsProvider().setCredentials(
new AuthScope(realm, port),
new UsernamePasswordCredentials(userName, password));
Firstly, I can't seem to set pre-emptive authentication using as a guide
the sample from http://hc.apache.org/httpclient-3.x/authentication.html
- I can't seem to find the method
client.getParams().setAuthenticationPreemptive(...);
Preemptive authentication in HttpClient 4.0 works completely differently
compared to 3.x.
Here's a sample application showing how HttpClient can be customized to
authenticate preemptively using BASIC scheme
http://svn.apache.org/repos/asf/httpcomponents/httpclient/trunk/httpclient/src/examples/org/apache/http/examples/client/ClientPreemptiveBasicAuthentication.java
Secondly, from inspecting the logs issued by the client, it appears that
the authorization request header that I'd expect to see is not there.
Most likely the auth scope is wrong

new AuthScope(realm, port)

The fist argument is hostname, not realm
Hope this helps

I'm obviously missing something obvious, but for the life of me, can't
find what it is. Any help gratefully accepted.
