title: jquery ajax call not working?! firefox or xss problem?
body: <p>My problem is: in firefox i got no response. in ie it worked fine.
  I want a ajax call to a local script getting some information in plain text or something else. but it won't work. I think cross scripting should not a problem at this point or?</p>
  
  <p>the javascript code is simple:</p>
  
  <pre><code>var targetUrl = "http://localhost/jQueryProxy.php";
  var parameters = ""; // later
  
  $.ajax({    
    type: "GET",
    async: true,
    url: targetUrl,
    data: parameters,
    success: function(param1, param2){
      alert(param1);
    }
  });
  </code></pre>
  
  <p>and the php code too:</p>
  
  <pre><code>&lt;?php
     header('Content-type: text/xml'));
     echo "test";
  ?&gt;
  </code></pre>
