Application layer attacks use more sophisticated mechanisms to achieve hacker targets. Application layer attacks do not use traffic or sessions to flood the network, but slowly deplete resources on the application layer for specific applications/services. Application layer attacks are very effective at low traffic rates. From a protocol point of view, the traffic involved in the attacks may be legitimate. This makes application layer attacks more difficult to detect than other types of DDoS attacks. HTTP flood, DNS dictionary, Slowloris, and so on are examples of application layer attacks.苞谷回到自己院子，也不梳洗，却吩咐丫头道：老鬼在哪儿？去，马上把他给我叫来。　　每一天都在认认真真生活的恩秀(柳真饰)自从失恋以后人生变得十分空虚。就在她失恋后的那段时间里发现了总到图书馆看198页书的那个男人，恩秀对这个男人越来越好奇……苏姑娘，祝福你和小鱼儿白头到老。　　上世纪70年代，在董家庄插队的百合遭遇情变，并被查出怀有身孕，受到村里恶人欺辱。同村哑巴董大山伸出救援之手，默默关心和保护着百合。百合生下儿子，母亲要她弃子回城，她割舍不掉，抱子和大山成亲。其他知青返城后，她独自留下来，和大山生下哑女。为给女儿治病欠下巨额债务，她走上打工还债之路。还清债务后，她艰难创业，历经坎坷，终于将父亲当年创下的“百家鸡”干得风生水起。与此同时，在百合的支持和帮助下，热爱艺术的大山获得成功，叛逆的儿子重返课堂，美丽的女儿考上职业学院。百合返回董家庄，携手曾经插队的同学们共建美丽乡村。村民们举行换届选举，一致推举百合为村委会主任。在第二故乡，百合和大山相亲相爱，如花绽放。Top, top, top!
