3 ile Dosya yükleme sorunu - MultipartException, bağlantı sıfırlama

Question

Bir pdf dosyası yüklemek için bir "dosya" alanı içeren bir web uygulamasına ait bir form var. (Bahar 3 çevre, çok parçalı dosya yükleme) Dosya yükleme iyi çalışıyor test ortamında (tüm tarayıcılarda) ve yalnızca üretim ortamında Firefox ile çalışır (dosya yükleme, özellikle düşük internet bağlantısı istemci tarayıcısına sahip bağlantı yükleme istisnasına neden olur)

Aşağıdaki istisna, gönderme düğmesine basıldıktan birkaç saniye sonra atılır: (tarayıcı IE/Chrome Windows ortamında çalışıyor ancak Firefox değil)

Bu istisnanın olası nedenler ne olabilir ? dosya yüklemesinde
Bağlantı sıfırlama genellikle istemci ne olmuş ... gönderme iptal demektir? Herhangi bir Yardım için teşekkür ederiz. Christophe D.

Answer 1

istemci ve sunucu arasındaki tcpdump yakalamak ve bağlantı sıfırlama kimin görebiliyor. Başvurumuzda da benzer bir sorun vardı ve bağlantıyı kesen bir güvenlik duvarıydı. Dosya yüklendikten sonra bu sınırı aşan apache [LimitRequestBody] adlı başka bir ayar daha vardı. Bu iki durumda apache ve mod-jk günlükleri, bu senaryolarda hata ayıklamak için çok açık değildi. Eğer html formu gönderebilir
