Hello Hernan,

Thanks for your answer.

Is there a way of knowing whether the dialog box that
comes up on my client site requires NTLM or Basic authentication?

As I said, the dialog comes up whichever site you visit using
a web browser - I assume it must be something they have set up
on their firewall.

Will it matter if I just use "Negotiate"?

Also, if I add several NetworkCredential objects to my cache, and add
this cache to my proxy, will it use all of the credentials in the
cache to authenticate until one succeeds?

Thanks in advance,

Akin
