以下の html を見て、リモート スクリプト (「http://code.katzenbach.com/Default.aspx」にあります) を読み込もうとすると IE6 がフリーズする理由を教えてください。スクリプトは JSONP を返し、ヘッダーにリストされている「callbackFunction」を実行します。正常に実行されると、1 ～ 500 の番号を示すポップアップ アラートが表示されます。これは FF3 と IE7 で正常に動作します。Internet Explorer 6 で失敗する理由がわかりません。プロセッサが固定され、すべてがハングします。

自分で実行して、同じ問題が発生した場合はお知らせください。私は一日中この問題を見つめてきました。ご協力いただきありがとうございます。

私は Fiddler と IE6 を調べましたが、異常なことは何も見られませんでした (ブラウザがフリーズするという事実以外に)。

へのリクエストhttp://code.katzenbach.com/Default.aspx?callback=callbackFunction&test=true&c=500が行われ、2909 バイトが返されます。

私は3つのことを提案します：

  1. Content-Type からセミコロンの 1 つを削除します。application/json;; charset=utf-8または、両方のセミコロンをcharset=utf-8完全に削除することもできます (テストのため)。
  2. )最終の送信が終わったら、改行文字を送信しますcallbackFunction
  3. 実際にブラウザに Javascript を返しているため、これを に変更しContent-Type: text/javascriptます。他のコンテンツ タイプは IE6 を混乱させる可能性があります (ほとんどありませんが)。

1.の可能性が高いと思います。IE6 には、2 つのセミコロンがあるとエンドレス ループに陥る原因となる解析バグが存在する可能性があります。そうでなければ、あなたがやっていることはうまくいかない理由がないからです。

テストとして別の MIME タイプを試すことも価値があるかもしれません。

なぜこれを警告したいのですか？
どのような問題を解決しようとしていますか?

スクリプト ( http://code.katzenbach.com/Default.aspx?callback=callbackFunction&test=true&c=500 )に直接アクセスすると、ファイル (未知の MIME タイプ) が処理されていないことがわかります。これは、サーバーのセットアップに問題がある可能性があります。.aspx を処理する方法を認識していないようで、代わりにファイルをストリーミングしようとしています。
