Açıklamalar

yöntemi, GetProxy parametresinde belirtilen İnternet kaynağına yönelik istekleri işleyen proxy sunucusunun URI'sini destination döndürür. GetProxy Yöntem null veya destination kendisi döndürürse, ana bilgisayarla iletişim kurmak için proxy kullanılmaz ve istek doğrudan sunucuya geçirilir.
