title: Ajax GET request turning into OPTION request
body: <p>I'm experiencing a weird behavior with an ajax request on a godaddy shared linux server. 
  The request works perfectly on many other servers I've tested it on, but on this one, the GET request turns into an OPTIONS request for some reason.</p>
  
  <p>Here's the js code (using mootools 1.1):</p>
  
  <pre><code>var a = new Ajax(myurl,{
              method: 'get',
              onComplete: function( response ){
                  $('my_div').style.display="none";
                  output_display( response );
              }
          });
          a.request();
  </code></pre>
  
  <p>You can see that the method is defined as GET. Yet when I watch the request happen with Firebug, it gets passed as an OPTIONS request. Any thoughts on how or why this would happen?</p>
