title: download csv (or other non html data) with phantomjs
body: <p>How can I access simple csv data?</p>
  
  <pre><code>    var webpage = require('webpage');
      var csvPage = webpage.create();
      var csvUrl= "http://www.scoach.ch/arcmsdownload/023c5c5aa58e6e0ff963ddcdea5ac016/CONTENT.csv/derivatives_2013-05-24.csv";
  
      csvPage.open(csvUrl, function(status){
        console.log("csv: " + csvPage.content);
      });
  </code></pre>
  
  <p>This will give me just an empty html:  which is not the expected result :-) I have tried several callbacks, but nothing helped me. </p>
  
  <p>Thanks for your Help!</p>
