Programming :: Interacting With A Website Using Perl And LWP?

I'm trying to write a Perl script that will go out to a website, log in, pull up a query page, fill-in and submit the query, extract a few specific lines from the query results, and finally place that output into a file. I'm having difficulty with the log in portion. It appears that rather than using the built-in Apache authentication, the developer decided to write their own authentication scheme that uses cookies.

I setup a cookie jar but I'm not certain I'm actually getting and keeping the cookie. When I try to go to a page after the log in page I get an error saying I'm not logged in or my session has expired. Here's the code as I have it thus far.

Code:
#!/usr/bin/perl
use strict;
use LWP;
use HTTP::Cookies;
