i am an external IT worker for a company that uses your excellent WinHttrack
program.
They have a Windows 2000 server with an ISA server 2003 proxy. So all
connections to internet requires to connect to a proxy, port 8080, with a
login and password.

The proxy parameters (server, port, login & password) are correct in the
winhttrack window but they have systematically a "407 Proxy Authentication
Required".

It seems that the program and the proxy are not talking the same language... I
know that there are a lot of types of proxy (Socks4, Socks4A, Socks5, ...) and
a lot of variation in the combination of login/pass/server/port.

Do you know a way to use winHttrack with ISA Server proxy ?

Thank you very much.
