How can I configure HTTPClient to authenticate against a SOCKS proxy?

Question

I need to set up proxy authentication against a SOCKS proxy. I found out this post giving instructions that appear to work with common HTTP proxies.

Answer 1

I tried

System.setProperty("socksProxyHost", "socks.xyz.com");
System.setProperty("socksProxyPort", "1000");

and it's working fine.
