title: Uploadify plugin in ASP MVC display HTTP 302 error
body: <p>I have implemented Uploadify plugin on my site (site has authentication/authorization implemented). And it works fine except it display me 302 HTTP error. <br/>
  I google a little and find <a href="http://trycatchfail.com/blog/post/2009/05/13/using-flash-with-aspnet-mvc-and-authentication.aspx" rel="nofollow">this article</a> but I still missing something. I suspect that error is somewhere in JS part. I saw similar questions here on stack and read them all but still have a problem :(</p>
  
  <pre><code>&lt;script&gt;    
      $(document).ready(function () {
          $('#file_upload').uploadify({
              'uploader': '../../Scripts/uploadify/uploadify.swf',
              'script': '../../ImageController/UploadImage',
              'cancelImg': '../../Scripts/uploadify/cancel.png',
              'scriptData': { 'token': '@Request.Cookies[FormsAuthentication.FormsCookieName].Value' },
              'folder': '/uploads',

              'buttonText': 'Upload image',

              onError: function (event, queueID, fileObj, errorObj) {
                  alert("Error!!! Type: [" + errorObj.type + "] Info [" + errorObj.info + "]");
              }
          });
      });
  &lt;/script&gt;
  
  [HttpPost]

              FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(token);
              if (ticket != null)
