The difference between the version which doesn't

# Show this #!? cookie
print Dumper $cookie if $option->{verbose};

# list archives
$request =
  HTTP::Request->new(
    GET => "https://$option->{hostname}/storiqone-backend/api/v1/archi
+ve/" );
$request->content_type('application/json');
[download]

and the version which just frigging works

# list archives
$request =
  HTTP::Request->new(
    GET => "https://$option->{hostname}/storiqone-backend/api/v1/archi
+ve/" );
$request->content_type('application/json');
$request->header('Cookie' => $cookie);
[download]

is that in the former you don't add the cookie to the request header, but in the latter you do. What do you expect? Do you expect that $ua shoehorns its cookie-jar into the new HTTP::Request object? You are expecting too much magic, I guess ;-)
