title: Send post with Spark Framework
body: <p>From what I understand the <a href="http://sparkjava.com/documentation.html" rel="nofollow">Spark Framework for Java</a> makes it very easy to run a restful server that accepts, POST, GET, etc..</p>
  
  <p>Is there an easy way to send a POST out using the spark library?</p>
  
  <p>The idea is to handle requests asynchronously and to respond via a callback. That callback requires an asynchronous post to come from my application to another web server.</p>
