- * Cookie Jar
- *
- * PHP class for handling cookies, as defined by the Netscape spec:
- * <http://curl.haxx.se/rfc/cookie_spec.html>
- *
- * This class should be used to handle cookies (storing cookies from HTTP response messages, and
- * sending out cookies in HTTP request messages). This has been adapted for FiveFilters.org
- * from the original version used in HTTP Navigator. See http://www.keyvan.net/code/http-navigator/
- *
- * 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, not RFC 2965.
