Straight from the POD of CGI.pm

To create a cookie

$cookie = $query->cookie(-name=>'sessionID',
                 -value=>'xyzzy',
                 -expires=>'+1h',
                 -path=>'/cgi-bin/database',
                 -domain=>'.capricorn.org',
                 -secure=>1);
print $query->header(-cookie=>$cookie);

To retrieve a cookie, request it by name by calling cookie() method without the -value parameter

use CGI;
    $query = new CGI;
    $riddle = $query->cookie('riddle_name');
        %answers = $query->cookie('answers');
