Bypass DNS lookup and submit URL to proxy

I have Java application that uses Apache HttpComponents to make web request. I have configured the application to use Proxy Servers using the JVM Property

java -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=3132

Currently my java application client makes DNS lookup in which it will fail. I want the Proxy to do the DNS resolution just like how web browsers do in automatic Proxy configuration mode (with .pac files).

Just for the record this how one can make HttpClient pick up system proxy settings

CloseableHttpClient client = HttpClients.custom()
    .setRoutePlanner(
         new SystemDefaultRoutePlanner(ProxySelector.getDefault()))
    .build();

or this if you want HttpClient fully configured based on system prperties

CloseableHttpClient client = HttpClients.createSystem();

Try looking here: http://hc.apache.org/httpcomponents-client-ga/httpclient/examples/org/apache/http/examples/client/ClientExecuteProxy.java

It seems as though you need to specify a proxy using setProxy() and not global properties.
