Works for me once you define the variables being passed into the cookie method. 

#!/usr/bin/perl -w
use strict;
use CGI;
use CGI::Cookie;

my $q = CGI->new();

my ($username, $secret) = ('wowza','special');


my $set_username = $q->cookie(
      -name => "user_name",
      -value => $username,
      -expires => "+1d",
    );


    my $set_session = $q->cookie(
      -name => "session",
      -value => $secret,
      -expires => "+1d",
    );


print $q->header( -cookie=>[$set_session, $set_username], $q->redirect
+(q|http://www.google.com/|));
#print $q->header();
print $q->html($q->body($q->h1('hi there')));
1;
