OK here is the answer. I know i posted the question but someone gave m
+e the answer in the 
silly chatbox thingy and didnt post it.

The documentation of HTTP::Cookies clearly states that it doesn't hand
+le
Set-Cookie3 format. Although the cookies will be in the response objec
+t the
$cjar->extract and $cjar->save methtods won't work with that format.

my thanks to tilly i believe it was who sorted out an answer.

Hence this workaround:

#!/usr/bin/perl

use URI;
use LWP::UserAgent;
use HTTP::Request;
use HTTP::Headers;
use HTTP::Response;
use HTTP::Cookies;
# Create a cookie jar. Hard coding the name of the file so we can keep
+ track of them.
#putting in a headers object incase we need it later on.
$cookie_jar = HTTP::Cookies->new('cookies.txt');
$hdrs = new HTTP::Headers();

# get a url object and a request object so we can go cruseing down the
+ web

$url = new URI::URL('http://foo.com');
$req = new HTTP::Request(GET, $url, $hdrs);

#make a useragent so we can spoof the server as to what client we actu
+ally are

$ua = new LWP::UserAgent;
$ua->agent('Mozilla/4.0 (Compatable; MSIE 5.01; Windows NT 5.0)');

# Send out the request
$responce = $ua -> request($req);

#save our cookies for a rainy day in cookies.txt

# here is the workaround for the moment. Passing a reference to the
# cookie jar to a hand rolled subrouteen.
save_cookies(\$cookie_jar);

# do the rest of the script as written before.
if($responce->is_success) 
{
    print $responce->content;
}
else
{
    print $responce->error_as_HTML;
}

# Write our own subrouteen for saving the cookies off.
sub save_cookies()
{
    my $cjar = ${+shift};
    my $cookies = $cjar -> as_string();
    my $c, $cr;
    $cookies =~ s/Set-Cookie3:\s//g;
    my @cookies = split(/\n/, $cookies);
    open(FILE, '>cookies.txt');
    foreach $c (@cookies)
    {
        @crumbs = split(/;\s/,$c);
        foreach $cr (@crumbs)
        {
            print FILE $cr, "\n";
        }
        print FILE "\n";
    }
}


It should be possible to extend the HTTP::Cookies.pm to handle this Se
+t-Cookies3 format.
I'm printing up the code of Cookies.pm and taking it home this weekend
+ to see what i can
do about that for the time being. I would like to be able to post it h
+ere and get some feed
back in the future.
