title: Sending json with tsung POST request
body: <p>I'm trying to create a POST request with Tsung</p>
  
  <pre><code>&lt;request&gt; 
    &lt;http url="api.whatever.com" method="POST" version="1.1" contents=""&gt;&lt;/http&gt;
  &lt;/request&gt;
  </code></pre>
  
  <p>How can I send a JSON document in the contents attribute?</p>
  
  <pre><code>contents='{"name": "alex"}' 
  </code></pre>
