Help with basic authentication
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(...);
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.
I'm obviously missing something obvious, but for the life of me, can't
find what it is. Any help gratefully accepted.

Help and contributions would be _very_ welcome.

Thanks very much, Oleg - that was a great help. The host name (not
realm) was the major problem. Also I hadn't realized that links in the
web site that explained authorization were only available for the older
version. Will these be updated at some stage to v4?
Cheers
John

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

Most likely the auth scope is wrong
---
new AuthScope(realm, port)
---
The fist argument is hostname, not realm
Hope this helps

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

new AuthScope(realm, port)

The fist argument is hostname, not realm
