Unfortunately, the proxy connection is still not working. I'm in the position
where I guess I have to use an NTLM proxy. This proxy does not require
authentication (for example, I can configure my web browser to point to
proxy.server.com:8080 and the web browser connects fine) However, whenever I
try to do this from my Java app, I always get a "access denied" page from the
proxy. Here is what I've tried for my HttpClient proxy configuration:
HttpHost proxy
= new HttpHost("proxy.server.com", 8080);
httpClient.getParams().setParameter(
ConnRoutePNames.DEFAULT_PROXY, proxy
);
AuthScope authScope = new AuthScope("proxy.server.com", 8080,
"[REALM]", "ntlm");
Credentials credentials = new NTCredentials("[MY_NT_USERNAME]",
"[MY_NT_PASSWORD]", "[WORKSTATION]", "[DOMAIN]");
httpClient.getCredentialsProvider().setCredentials(
proxyAuthScope, proxyCredentials
);
Now, I'm not exactly sure what the exact values are suppose to used for
"[REALM]", "[MY_NT_USERNAME]", "[MY_NT_PASSWORD]", "[WORKSTATION]", and
"[DOMAIN]", but I have tried a number of different combinations and have yet to
hit a working solution.
Any additional thoughts?

Absolutely. HttpClient will make use of them as needed.
