Need help with servlet exception error

(Note: I actually posted this message via the Yahoo Groups interface, 
but then realized that hadn't been updated since 2001. So, assuming this 
list is still active, this may be a dupe posting - I apologize in 
advance. This particular problem has been plaguing me for about 4 
months. I'm hoping that somebody has a solution.)

I'm trying to hit this URL (corporate intranet):

https://www.dmotorworks.com/ia.ui/broker/login

.... using the following code:

use LWP;
my $URL = "https://www.dmotorworks.com/ia.ui/broker/login";
my $browser = LWP::UserAgent->new( );
my $response = $browser->get($URL);
print $response->content;

When I go to that URL using Firefox or IE, I get a login screen. When
I try it using LWP, I get a 'servlet exception error'.

I nstalled Crypt::SSLeay (WinXP SP2 and ActivePerl) via the instructions 
here:
http://johnbokma.com/perl/https.html

I'm able to reach https sites (such as https://www.paypal.com), but
not the one I mentioned above.

Hoping somebody can tell me what I am missing!
