multipart / form-dataリクエストの処理に失敗しました。タイムアウトしました

スタックオーバーフローに関する他の質問がこの質問に対処しましたが、提供された回答のいずれも、この問題の解決に役立ちませんでした。

Apache HTTP Commonsを使用して、アプレットから10 kB〜16 MBのファイルをアップロードしようとしています。私のローカル環境ではすべてがうまく機能します。

ファイルサイズに関係なく、実稼働サーバー（Tomcat 6.0、 https://www.dailyrazor.com/ ）でのみ次の例外を受け取ります。

このアップロードの問題以外では、アプレットは正常に動作します。

これは、実稼働サーバーのserver.xmlファイルで説明されているサーバーの構成です。

<!-- Define an AJP 1.3 Connector on port 8009 --> <Connector address="127.0.0.1" port="9609" enableLookups="false" protocol="AJP/1.3" connectionTimeout="30000" maxThreads="50" minSpareThreads="1" maxSpareThreads="3" disableUploadTimeout="true" />

インターネット接続の速度は良好（2.01 Mbpsダウン、0.42 Mbpsアップ）なので、この例外は私を困惑させます。既にconnectionTimeOutを3000000に設定していますが、それでも例外があります。 connectionTimeOutを-1に設定して無制限にする必要がありますか？

ファイルのアクセス許可は、アップロード元のディレクトリで777に設定されており、JDKバージョン7を使用してブラウザでアプレットを実行しています。

Javaコンソール出力：

iは、これが私のISPの問題である可能性があることを知りました。 temviewerやSkypeなどのソフトウェアをスムーズに使用できるのはなぜiSPの問題なのだろうか？

アップロードを実行するコードは次のとおりです。

public static String uploadUsingApache(URL url, List<File> list,
            String userId, String accountId, String waveDuration)
            throws Exception {

        // The execution:
        DefaultHttpClient httpclient = new DefaultHttpClient();

        HttpPost method = new HttpPost(url.toString());

        MultipartEntity entity = new MultipartEntity();
        entity.addPart("userId", new StringBody(userId, Charset
                .forName("UTF-8")));
        entity.addPart(IVR_ACCOUNT_KEY, new StringBody(accountId, Charset
                .forName("UTF-8")));
        entity.addPart(IVR_MP3LEN_KEY, new StringBody(waveDuration, Charset
                .forName("UTF-8")));

        // FileBody fileBody = new FileBody(list.get(0));
        // entity.addPart("file", fileBody);

        for (File f : list) {

            byte[] imageBytes = fileToByteArray(f);
            entity.addPart("attachment_field", new InputStreamKnownSizeBody(
                    new ByteArrayInputStream(imageBytes), imageBytes.length,
                    "audio/wav", f.getName()));
            method.setEntity(entity);
        }

        ResponseHandler<String> responseHandler = new BasicResponseHandler();

        // HttpResponse response = httpclient.execute(method,responseHandler);
        String responseText = httpclient.execute(method, responseHandler);

        // error text
        if (responseText.contains("<exception>")) {
            responseText = responseText.replace("<exception>", "");
            responseText = responseText.replace("</exception>", "");
            throw new Exception(responseText);
        }

        // System.out.println(" Status " +response.getStatusLine());
        List<String> deleteList = Arrays.asList(responseText.split(","));

        StringBuffer sb = new StringBuffer();
        int cnt = 1;
        for (File f : list) {
            if (deleteList.contains(f.getName())) {
                sb.append(f.getName() + (cnt == deleteList.size() ? "" : ", "));
                f.delete();
                cnt++;
            }

        }

        if (deleteList.size() > 1) {
            sb.append(" are ");
        } else if (deleteList.size() == 1) {
            sb.append(" is ");
        } else {

        }

        sb.append(" successfully saved.");

        return sb.toString();
    }

アプレットのGUIでアップロードボタンを押すと、上記のメソッドが呼び出され、同時にGUIがフリーズします。 10〜50秒後、サーバーはFileUploadExceptionをスローします。サーブレットはアプレットに例外を通知しますが、アプレットはユーザーに例外を通知する前に4〜5分間ハングします。

サーバー側に何か問題がある場合、なぜそんなに遅延があるのですか？

これは私を大いに助けてくれました： http://blog.somepixels.net/en/502-proxy-error-uploading-from-Apache-mod_proxy-to-Tomcat-7/

基本的に、server.xmlで次のように設定します。

<Connector port="8080" protocol="HTTP/1.1" URIEncoding="UTF-8"
       connectionUploadTimeout="36000000" disableUploadTimeout="false"
       connectionTimeout="60000" redirectPort="8443" />

実行中の設定（または既に試した設定）の質問からは明らかではありませんが、問題はほとんどの場合、アップロード中にソケットタイムアウトを超えていることです。

関連するタイムアウトに達する前にファイルが完全に受信されなかったため、エラーがスローされます。これは、テスト（ローカルネットワーク上）で動作しているものと一貫していますが、非常に低速のインターネット上で実行している場合（特に、アップロード速度に関して）ではありません。

server.xml関連する<Connector>定義。 connectionTimeout属性またはconnectionUploadTimeout属性（disableUploadTimeoutがtrueに設定されている場合は後者）のいずれかの値に関心があります。

より悪質な問題の証拠がない場合、接続タイムアウトを増やすだけでこの問題を解決できると期待しています。
