In the process of DNS resolution, the client initiates a query request, and the DNS server may need to make additional queries to complete the resolution process and give a response, which will consume certain computing and network resources. If an attacker uses a large number of controlled hosts to continuously send resolution requests for different domain names, the cache of the DNS server will be continuously refreshed, and the failure of a large number of resolution requests to hit the cache will cause the DNS server to consume additional resources for iterative queries, which will greatly increase the resource consumption of the DNS server.

电影剧本会由侯孝贤和朱天文以及阿城帮忙打造，目前定下的演员只有舒淇和张震，金城武、浅野忠信等人也在接洽中。《聂隐娘》对侯孝贤的最大挑战是商业诉求，他的作品除了出道时候的喜剧片和少数几个片子，其他无一例外丧失了本岛市场，只能走上无奈的国际影展路线。侯孝贤如何在商业导向的压力下保持个人风格以及创作自由，他能作出何等改变将是一大看点。此外由于杨德昌没能完成北宋的追风少年（资金缺口太大），侯孝贤梦回唐朝的侠女传奇更是多出一番意义。
