Hi Mario.

Here is an update on the HttpClient testing I've done.

I've been playing around with HttpClient 3.0.1 (stable release) for a
while now and it looks like you can do the double authentication. (well
authentication to a site plus proxy authentication) I don't think the
version of HttpClient that is being used with the current version of VFS
(HttpClient version 2.0.2) can do it though.

Our company has set up Microsoft ISA to use NTLM version 2 and Kerberos
as the authentication schemes for the proxy so even HttpClient 3.0.1
cannot get through (as it does basic, digest and NTLM version 1 only).

I believe HttpClient 3.1 can do it but that is currently only in an
alpha state so I don't think I'd use that just yet.

So I think I'm stuck on that front.

FTP is probably my best bet. (that, I know, isn't being proxied)

Anyway, I thought you'd like to know.

All the best,
