No you I don't think you did. Since it sent no Location: header it didnt't
redirect, it was just the server that decided to respond back to you with some
contents that you didn't expect. Perhaps the same contents as the login.jsp
page.

This is most likely not curl's fault since the command line version works. I
would guess that the server is stupidly doing this due to the lack of
user-agent field.

There is no "login" for this, the autentication credentials are passed on in
the request for that single page.

You didn't use cookies for the command line version.

Cookies are very seldom for a specific page, they are for domains and paths.
And since the server didn't do any redirect, it _is_ the same page both
approaches get, it is just different contents (and cookies apparently) and
that's a server-side decision.

I tend to always recommend the latest version (unless something really weird
is going on) and I still do. However, I don't think you suffer from a libcurl
bug so I doubt it'll change the behaviour for you.

I can't say anything about the curlpp version as I know nothing about it.
