Just one (relatively minor) addition: only Basic authentication can be used preemptively. NTLM authentication scheme is stateful (that is, NTLM authentication process spans across several requests/responses) and therefore NTLM credentials cannot be used outside a valid authentication context.
Saifadam, Do you intentionally use preemptive authentication or was it the only you could get the proxy authentication work for you? Are you using HTTPS by any chance?

If it is a Microsoft proxy you need to use NTLM authentification which requires NTCredentials. http://jakarta.apache.org/commons/httpclient/authentication.html contains some further infos. At least that was what I needed.
