Hi, I am trying to write a perl script which passes through our firewall. We have a system at work which requires a separate user name/ password which is needed to access the global internet and if you do not make an HTTP request for a certain period of time, then you have to re-login. Now, ordinarily, this is not a problem since I just run one of those news alert programs which checks for news every 5 minutes and so it's not a huge bother. However, I have a few processes that I run with "at" (Win NT 4.0) on the weekend, and I would like to ensure that these run by running this script first.

I've Googled and SuperSearched and still no luck. What I have so far (pretty much copied from the perl cookbook & the LWP docs) is the following:

use strict;
use diagnostics;
use LWP::UserAgent;
use HTTP::Request;
use HTTP::Response;
my $ua = LWP::UserAgent->new();

$ua->agent("Test/0.01");
$ua->credentials('mysite', 'myrealm', 'myuserid','mypassword');

my $req = HTTP::Request->new('GET', 'http://www.yahoo.com');

my $response = $ua->request($req);

if ($response->is_error()) {
    printf " %s\n", $response->status_line;
}
else {
    print $response->content();
}

This returns 401 Unauthorized as the status line when my firewall connection is inactive (i.e. more than X minutes have elapsed (and my correct site, realm, username, password are filled in)

Normally, if I try to login through the firewall for the first time by typing in an external URL, it prompts me with the familiar dialog box (Site/Realm/Username/password). If I hit cancel, it redirects me to http://{IP address of firewall machine}/fwauthredirect{ip address of web server}id{a numeric code, looks to be a sequence number}

Thanks for any insight you can provide. If I left out any info you need, let me know.
