The following set of statements helped me to send requests through Proxy.
Hope this example can help you.
httpClient.getHostConfiguration().setProxy(proxyHost,proxyPort);
AuthScope as = new AuthScope(proxyHost,proxyPort);
httpClient.getState().setProxyCredentials(as, new
NTCredentials(proxyUserName,proxyUserPassword,InetAddress.getLocalHost().getHostName(),networkDomainName));
Note: If you have problem with the trusted certificates, you can try
not-yet-commons-ssl.
Thanks,
Arun Kumar Dubagunta
