Using Selenium RemoteWebDriver behind corporate proxy

Question

How can I connect to a selenium grid such as BrowserStack via RemoteWebDriver from behind a corporate proxy?

The application under test is outside the proxy and free

I've reworked Andrew Sumner's solution slightly and taken some out in case someone like me wants to just quickly funnel their WebDriver traffic through Fiddler to see the traffic.

import java.net.MalformedURLException;
import java.net.URL;
import java.util.HashMap;

import org.apache.http.HttpHost;
import org.apache.http.impl.client.HttpClientBuilder;
import org.openqa.selenium.ie.InternetExplorerOptions;
import org.openqa.selenium.remote.CommandInfo;
import org.openqa.selenium.remote.HttpCommandExecutor;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.remote.http.HttpClient;
import org.openqa.selenium.remote.http.HttpClient.Factory;
import org.openqa.selenium.remote.internal.ApacheHttpClient;

public class ProxiedRemoteExample {
    private static final String PROXY_HOST = "localhost";
    private static final int PROXY_PORT = 8888;

    public ProxiedRemoteExample() throws MalformedURLException {
        InternetExplorerOptions ieOptions = new InternetExplorerOptions();
        RemoteWebDriver driver = new RemoteWebDriver(new HttpCommandExecutor(new HashMap(),
                new URL("http://localhost:5555/"), new Factory() {
                    private HttpClientBuilder builder;
                    {
                        builder = HttpClientBuilder.create();
                        builder.setProxy(new HttpHost(PROXY_HOST, PROXY_PORT));
                    }
                    @Override
                    public HttpClient createClient(URL url) {
                        return new ApacheHttpClient(builder.build(), url);
                    }

                }), ieOptions);
    }

}
