If you use LWP::UserAgent you can use HTTP::Cookies to create a cookie jar, like:

use HTTP::Cookies;
 $cookie_jar = HTTP::Cookies->new;
[download]

Then set this cookie_jar to be used in the user agent.

$ua->cookie_jar([$cookie_jar])
[download]

You can extract and add cookie like:

$cookie_jar->extract_cookies($response);
$cookie_jar->set_cookie($version, $key, $val, $path, $domain, $port, $
+path_spec, $secure, $maxage, $discard, \%rest)
[download]

Hope that helps..
