multipart/form-data要求の処理に失敗しました。 Read timed out

Question

Stack Overflowに関する他の質問がこの質問に対処しましたが、提供された回答のどれもが私の問題に対処できませんでした。

私は、Apache HTTP Commonsを使用しているアプレットから10KBから16MBの間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動作します。

私は、ファイルサイズに関係なく、唯一の私の本番サーバー（Tomcatの6.0、https://www.dailyrazor.com/）に次の例外を受けています：

このアップロードの問題以外、私のアプレットは正常に動作します。私の運用サーバーのserver.xmlファイルに記載され

これは、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" /> 

私のインターネット接続の速度は、（ダウン2.01 Mbpsおよび0.42 Mbpsのアップ）で結構ですので、この例外は私の葉困惑した。私はすでにconnectionTimeOutを3000000に設定しましたが、私はまだ例外があります。無制限にするためにconnectionTimeOutを-1に設定する必要がありますか？

ファイルのアクセス許可は、私がアップロードしているディレクトリの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：

Java Plug-in 10.7.2.10 
Using JRE version 1.7.0_07-b10 Java HotSpot(TM) Client VM 

アップロードが失敗したとき、私はコンソールでこれを取得する：

私は、これは私のISPの問題であるかもしれないことを知るようになってきました。なぜ私はスムーズにtemviewerやSkypeのようなソフトウェアを使用することができるのiSPの問題ですか？私は、アプレットのGUI上のアップロードボタンを押すと

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(); 
    } 

、それはGUIがフリーズ法上、同時に呼び出します。

次は、アップロードを実行するコードです。 10〜50秒後に、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について通知しますが、アプレットは4〜5分間ハングしてからユーザーに例外を通知します。

サーバー側に何か問題があると、それほど時間がかかるのはなぜですか？

Answer 1

これは多くの私を助けた：私のserver.xmlの基本的http://blog.somepixels.net/en/502-proxy-error-uploading-from-apache-mod_proxy-to-tomcat-7/

として、私はそれを設定する：あなたは」同様の質問（複数可）にリンクされている場合、それが参考になる

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

Answer 2

実行中の設定（またはすでに試したもの）は問題ではありませんが、アップロード中にソケットのタイムアウトを超えてしまうという問題がほとんどあります。

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、ローカルネットワーク上のテストで作業しているものと一貫していますが、はるかに遅いインターネット（特にアップロードの場合）では動作しません。

該当する<Connector>の定義については、server.xmlをご覧ください。 connectionTimeoutまたはconnectionUploadTimeoutのいずれかの属性（後者はdisableUploadTimeoutがtrueに設定されている場合）の値に関心があります。

さらに悪質な問題の証拠がない場合は、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思います。
