Is it possible to use HTML/Javascript to browse another website

Is it possible to use HTML/Javascript to browse another website?
I am able to access a website (a wiki) using a browser. The site has a
Kerberos/SSO authentication mechanism, which I am unable to log in to
using anything other than Internet Explorer.
What I would like to do is to create a backup of the contents on the site
recursively (it is a Wiki). I tried this with Java, but I am unable to log
in. So I figured, can I create a HTML/Javascript tool that accesses the
site from within IE? I tried using frames, having my tool in one frame and
the Wiki in another, but that doesn't seem to work. Thanks, Kjeld
