title: Jquery .get() not working in Internet Explorer
body: <p>I'm having a problem with, guess what, IE8. The following code, simplified for clarity, does not work at all:</p>
  
  <pre><code>alert('before get');
  
  $.get(getActivityURL('ActionName',{
      ts: new Date().getTime(), ...other params...}), 
  {cache:false;},
      function (xml) {
      alert("in get callback");
  },'xml'); // End $.get()
  
  alert('in after get');
  </code></pre>
  
  <p>The getActivityUrl() outputs a valid URL with request parameters.</p>
  
  <p>This works correctly in FF and Chrome. However, in IE8, this doesn't even get into the $.get() callback. I get the "before" and "after" alerts, but not the "in" alert and indeed, nothing happens and the request is NOT sent. I don't really know what to think here.</p>
  
  <p>The response headers are "Content-Type:application/xml; charset:iso-8859-1" as confirmed in FF.</p>
  
  <p>EDIT: $.post() doesn't work, either.</p>
