ファイルをアップロードする際にバネ3でエラーが発生しました - MultipartException、接続がリセットされました

Question

私はPDFファイルをアップロードするための "file"フィールドを含むWebアプリケーションに属するフォームを取得しました（spring 3環境、マルチパートファイルアップロード） ファイルのアップロードは問題ありませんテスト環境（すべてのブラウザ）で動作し、実稼働環境ではFirefoxでしか動作しません（特に、インターネット接続クライアントブラウザが低いファイルアップロードの接続リセット例外）

サブミットボタンを押してから数秒後に例外がスローされます。ブラウザはIE/ChromeはWindows環境で動作しますがFirefoxでは動作しません）

のTomcat 6 AJPコネクターのコネクター構成： （元の構成でした。 ）

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443"/>

      connectionUploadTimeout="3600000" 
      disableUploadTimeout="true"

？
ファイルのアップロード時の接続リセットは、通常、クライアントが送信を中断したことを意味します。だから何ですか？ 助けていただければ幸いです。 Christophe D.

Answer 1

クライアントとサーバーの間でtcpdumpをキャプチャして、誰が接続をリセットしているかを確認できますか。私たちのアプリケーションでも同様の問題があり、ファイアウォールが接続を切断していました。ファイルのアップロードがその制限に達した後、アップロードを中止していたapache [LimitRequestBody]の別の設定がありました。これらの2つのケースでは、apacheとmod-jkのログは、これらのシナリオでデバッグするのにあまり明確ではありませんでした。
