A monk directed me to LWP::UserAgent. So here's where I am.

my $ua = LWP::UserAgent->new;
$ua->timeout(30);

my $response = $ua->get($redirectURL);
 
if ($response->is_success) {
    $logger->info("Grabbing data and passing it to browser.");
    print $response->content;  # or whatever
    $logger->info($response->content);
}
else {
    $logger->info("Didn't get the data.");
    die $response->status_line;
}

I'm seeing the "Grabbing data and passing it to browser." message, and the data in the browser looks like the PDF data I want, but I'm getting an Internal Server Error on the browser.

Thoughts?
