| 6 | * <http://curl.haxx.se/rfc/cookie_spec.html> | ||
| 7 | * | ||
| 8 | * This class should be used to handle cookies (storing cookies from HTTP response messages, and | ||
| 9 | * sending out cookies in HTTP request messages). This has been adapted for FiveFilters.org | ||
| 10 | * from the original version used in HTTP Navigator. See http://www.keyvan.net/code/http-navigator/ | ||
| 11 | * | ||
| 12 | * This class is mainly based on Cookies.pm <http://search.cpan.org/author/GAAS/libwww-perl-5.65/ | ||
| 13 | * lib/HTTP/Cookies.pm> from the libwww-perl collection <http://www.linpro.no/lwp/>. | ||
