Worked around the problem using ::
$URL = "http://www.sweetcombe-ch.co.uk/aspbooking/avail.asp?Propre
+f=".$AGENTid."&Classref=".$AGENTid." LOCAL&";
$ua = LWP::UserAgent->new;
$ua->cookie_jar(HTTP::Cookies->new(file => "c:/tmp/lib/lwpcookies.
+txt", autosave => 1));
$ua->agent("$0/0.1 " . $ua->agent);
$ua->agent("Mozilla/8.0"); # pretend we are very capable browser
$req = HTTP::Request->new(GET => $URL);
$req->header('Accept' => 'text/html'); # send request
$res = $ua->request($req); # check the outcome
if ($res->is_success) {
print $res->content;
} else {
print "Error: " . $res->status_line . "\n";
}
