Thanks, very good point... I rewrote the code to make a post request so I could pass it into my $mech

#List page is the BASE page from which I am starting

my $aspContent= $aspnet->httpRequest->content; 

my $req = HTTP::Request->new(POST => "$LIST_PAGE");
$req->content_type('application/x-www-form-urlencoded');
$req->content("$aspContent");
my $res = $mech->request($req);
if ($res->is_success) {
$content = $res->content;
        }
print $content;
[download]

So what I assume is that this should be sent like :
POST
Host: $LIST_PAGE
User-Agent: Mozilla/5.1
Content-Type: application/x-www-form-urlencoded
Content: With the content of the asp post here.
This runs but however still returns the base page. So I am still back where I started :(
