c# - Uploadify が FireFox ASP.NET で機能しない

Question

Uploadify を FireFox で動作させることができません。IE と Chrome で動作しています。

フラッシュ Cookie のバグに関する記事をいくつか読み、その修正を実装しようとしましたが、成功しませんでした。

ASP.NET WebApplication で動作させようとしています。誰かが同様の問題を抱えていたので、アドバイスをいただけますか？

  $(document).ready(function () {
            $('#fuFiles').uploadify({

                'script': 'FileUploads.aspx',

          * Since Flash Player always sends the IE cookies even in FireFox
          * we have to bypass the cookies by sending the values as part of the POST or GET
          * and overwrite the cookies with the passed in values.
          * 
          * The theory is that at this point (BeginRequest) the cookies have not been read by
          * the Session and Authentication logic and if we update the cookies here we'll get our
          * Session and Authentication restored correctly
