uploader un fichier par FTP en DOS via un Proxy

Le
hackoo
Bonjour,
J'ai utilisé le programme ftp de DOS de Windows pour envoyer un fichier chaque jour avec Vbscript. Nous venons d'ajouter un serveur SQUID proxy dans notre réseau avec un Login et un Mot de passe utilisant le port 3128.
Ma question est la suivante: comment faire pour modifier cette Fonction Ftpupload pour résoudre ce probléme de Proxy?
Merci d'avance!
