title: HttpPost Request set multiple entities
body: <p>I have a <code>HttpPost</code> Request and I need to set multiple entities for it. I know that <code>setEntity</code> is used to set single entity.  </p>
  
  <pre><code>ObjectMapper mapper = new ObjectMapper();
              String json = "";
              json = mapper.writeValueAsString(object);
  
              StringEntity se = new StringEntity(json);
              se.setContentType("application/json;charset=UTF-8");
              se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,
                      "application/json;charset=UTF-8"));
  
              request.setEntity(se); 
  </code></pre>
  
  <p>But how to set multiple entitiesin the request?</p>
