Ho ottenuto un modulo appartenente a un'app Web che contiene un campo "file" per caricare un file pdf. (Ambiente spring 3, caricamento file multipart) Il caricamento del file funziona bene in ambiente di test (tutti i browser), e funziona solo con Firefox in ambiente di produzione (in particolare il caricamento del file causa un'eccezione di reset con basso browser di connessione Internet)Problema di caricamento file con molla 3 - MultipartException, reset connessione
La seguente eccezione viene lanciata pochi secondi dopo aver premuto il pulsante di invio: (browser è IE/Chrome in esecuzione in ambiente Windows ma non Firefox)

Quali potrebbero essere le possibili ragioni per questa eccezione ?
Il ripristino della connessione sul caricamento di file di solito significa che il client ha interrotto l'invio ... quindi cosa? Qualsiasi aiuto sarebbe gradito. Christophe D.
puoi pubblicare il tuo modulo html, sembra un problema con la codifica del modulo. –
hi Jigar, ho appena modificato questo thread, ora puoi vedere il modulo html. Grazie. –
Sono abbastanza sicuro di avere un firewall/bilanciamento del carico di fronte al server di produzione che sta terminando le connessioni dopo un certo timeout, anche se il server delle applicazioni consente un timeout di caricamento di grandi dimensioni. Quello che vorrei fare è provarlo in produzione con gli strumenti per sviluppatori aperti per vedere dopo quanto tempo il caricamento fallisce. Se noti che ad ogni istante l'errore si verifica esattamente dopo x secondi, sai che la tua infrastruttura sta chiudendo la connessione. – Akshay
