title: How to jQuery.post() with no data to send
body: <p>I'm not sure if I'm approaching this the correct way but I'm trying to send a small amount of data to the server and receive a couple of strings back.  Because of the way the server CMS works the data is most easily sent in the URL path so I have no need to send any additional 'data'.  For example :</p>
  
  <pre><code>      var url = '/footnotes/cleartile/'+nid+'/'+tid+'/'+side;
        var mydata = 'This serves no purpose';
        jQuery.post(url, mydata, function(data) {
          console.log("Data Loaded: " + data);
        });
  </code></pre>
  
  <p>Is jQuery.post() the correct mechanism for this type of communication ?  And if so, what should I pass in the data parameter when nothing is necessary ?</p>
