title: XMLHttpRequest responseText is empty
body: <p>I have read much on this site, but I can't solve my problem! :( 
  It must be very easy but it does not work! </p>
  
  <p>The problem is <code>http.responseText</code> is empty.</p>
  
  <p>I'm using the webspace on <a href="http://www.000webhost.com" rel="nofollow">http://www.000webhost.com</a></p>
  
  <p>Is it posible to get a String with the Sourcecode of <code>www.google.de</code>?</p>
  
  <p>Thanks for any help!</p>

  &lt;h1&gt;My Example&lt;/h1&gt;
  &lt;script type="text/javascript"&gt;
  
  var http = new XMLHttpRequest();
  
  http.open("GET", 'https://www.google.de', true);
  http.send(null);
  
  http.onreadystatechange = function() {
      alert(http.responseText);
  }
  
  alert("The end is reached");
  &lt;/script&gt; 
  
  
  &lt;b&gt;Here is some more HTML&lt;/b&gt;
