This class should be used to handle cookies (storing cookies from HTTP response messages, and sending out cookies in HTTP request messages).
This class is mainly based on Cookies.pm <http://search.cpan.org/author/GAAS/libwww-perl-5.65/
lib/HTTP/Cookies.pm> from the libwww-perl collection <http://www.linpro.no/lwp/>.
Unlike Cookies.pm, this class only supports the Netscape cookie spec
<http://wp.netscape.com/newsref/std/cookie_spec.html>, not RFC 2965.
