title: HTTP client for multithreaded application
body: <p>I'm implementing Java-based HTTP bot for performance testing purposes. Can anyone suggest Java HTTP client library, suitable for multithreaded environment.</p>
  
  <p>It looks like standard answer is <a href="http://hc.apache.org/httpcomponents-client-ga/index.html" rel="nofollow">Apache HTTP client</a>, but it's synchronous and it seems to me I need some async solution in this case.</p>
