Exemples

L’exemple suivant utilise la Credentials propriété pour définir les informations d’identification qui seront soumises au serveur proxy pour l’authentification.

Remarques

La Credentials propriété est une ICredentials instance qui contient les informations d’identification d’autorisation à envoyer au serveur proxy en réponse à un code status HTTP 407 (autorisation proxy).
