Is there some way I can back up a web page that prompts for
a password?  I know the password, I am not trying to crack
anything, just copy the website.

Background
----------
My goal is to document the settings used in my Linksys
network equipment devices. Each of these devices contain a
mini-web server to provide the user interface to configure
options.  SO for example, when you browse to
<http://192.168.1.1> it pops up a window requiring manual
entry of a password.

Thanks in advance for any tips or suggestions,
