And what about this node:
http://www.perlmonks.org/?node_id=532936
I'm really confused about this. I tried using the code below to set a cookie on a visitor's browser:

#- Set Cookie --------------------------------------------------------
+---------#
sub setCookie {
  # end a set-cookie header with the word secure and the cookie will o
+nly
  # be sent through secure connections
  my ($name, $value, $expiration, $path, $domain, $secure) = @_;

  print "Set-Cookie: ";
  print ($name, "=", $value, "; expires=", $expiration,
    "; path=", $path, "; domain=", $domain, "; ", $secure, "\n");
}

And it works fine on Firefox. On MSIE, cookies are saved on another file, named gabuleu.com (my domain name). When the user calls my website from a MSIE, nothing is retrieved. On the other side, when I test it using firefox, cookies are retrieved.Maybe CGI::Cookie handles this. I haven't tried it.
