title: How to check if proxy is used in HttpClient and how to turn the proxy off?
body: <p>My java desktop application uses httpclient as REST client. The communication (simple GET operations) is very slow. I think, the operating system (Windows 7) proxy settings are used, although the particular destination IP-address is excluded from the proxy settings. Somewhere must be the bottleneck.</p>
  
  <p>Is there a way to check if httpclient uses a proxy? If it so, how can I turn the proxy off (in httpclient).</p>
  
  <p>I already have tried to work with -Djava.net.useSystemProxies=false and so on; no effect.</p>
