title: Parameters to dojo.xhrPost
body: <p>When I use <code>dojo.xhrGet</code> , I use it this way to send more than one parameter via the <code>GET</code></p>
  
  <pre><code>dojo.xhrGet
  ({
      url:"MyServerPageURL?Param_A="+"ValueA"+"&amp;Param_2="+"Value2",
      load: function(data)
      {
          //do something
      },
      preventCache: true,
      sync: true, 
      error: function(err)
      {
          alert("error="+err); 
      }
  });
  </code></pre>
  
  <p>How could I do similar thing (send more than one parameter) when I have to use the <code>dojo.xhrPost</code> instead?</p>
