Apache HttpClient 4.1 - Proxy Authentication

Question

I've been trying to configure the user and password for proxy authentication from the configured properties while using Apaches HttpComponent's httpclient, but with no success. All examples I have found refer to methods and classes that are no longer available, such as HttpState and setProxyCredentials.

So, can anyone give me an example of how to configure the proxy credentials?

For anyone looking for the answer for 4.3...its fairly new and their example didn't use the new HttpClientBuilder...so this is how I implemented this in that version:

NTCredentials ntCreds = new NTCredentials(ntUsername, ntPassword,localMachineName, domainName );  CredentialsProvider credsProvider = new BasicCredentialsProvider(); credsProvider.setCredentials( new AuthScope(proxyHost,proxyPort), ntCreds ); HttpClientBuilder clientBuilder = HttpClientBuilder.create();  clientBuilder.useSystemProperties(); clientBuilder.setProxy(new HttpHost(pxInfo.getProxyURL(), pxInfo.getProxyPort())); clientBuilder.setDefaultCredentialsProvider(credsProvider); clientBuilder.setProxyAuthenticationStrategy(new ProxyAuthenticationStrategy());  CloseableHttpClient client = clientBuilder.build();
