+ * 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.
