title: How to Read the message Body in a HTTP POST in Netty (version >= 4.x)
body: <p>In my server handler;
  - channelRead() always gets the msg as HTTPRequest and there I cannot find any place to get the POST request payload. </p>
  
  <ul>
  <li>Then I tried following in my handler to check if it works. The decoder has 0 elements.</li>
  </ul>
  
  <p>HttpPostRequestDecoder decoder = new HttpPostRequestDecoder(new DefaultHttpDataFactory(false), request); </p>
  
  <p>In my server pipeline I have HttpServerCodec and a custom handler only.</p>
