The way of this attack is that the attacker can renegotiate quickly and continuously in an SSL connection, and the CPU overhead of the server is about 15 times that of the client when negotiating the encryption algorithm. If a large number of controlled hosts attack at the same time, the server will be busy negotiating the secret key and stop responding completely.　马师傅一日走在熙攘大街上，见绿草红花掩映间有华山二字。马师傅两目微合，开始了与各大武林高手对决的巅峰时刻。筹备好的节日晚宴，因为她要为一个临产的女青年墨非接生。 　　即将手术的时候，张静芳发现墨菲姑娘是一个单亲妈妈。随后医院里又冲进来一群不速之客——使墨非怀孕的男性一家赶来了，他们跟墨非的家人展开了尖锐的谈判，要求用金钱买走即将诞生的孩子。两下里讨价还价，舌剑唇枪，最终恶言相向，拍案走人。 　　孩子诞生了，张静芳为成功地迎来一个小生命而欣慰的同时，也为又一个单身妈妈而怜惜。正当疲惫的她准备回家时，噩耗传来——丈夫在驾车来医院接她的路上遇见车祸死亡。这一瞬间，张静芳也变成了无数个单亲妈妈中的一员。从此后，新的单亲妈妈张静芳，墨非，以及两个老的单亲妈妈西曼和米宝湘四人走到了一起，成为了“单亲妈妈四人组”。单亲妈妈的生活是艰辛的，坚持工作的同时还要养育孩子。另一方面，她们还要承受社会对她们的看法，毕竟“寡妇门前是非多”。更难过的是失去了丈夫之后所要承受的孤独和无助。Since http is based on tcp, You need to complete a three-way handshake to establish a tcp connection before you can start http communication, Therefore, when http flood attacks are carried out, it is not possible to use forged source ip addresses to launch attacks. An attacker will typically use an http proxy server, Not only can the source be hidden from being traced, It also improves attack efficiency-after the attacker connects to the proxy server and sends the request, You can directly disconnect from the proxy server and start connecting to the next proxy server, At this time, the http connection between the proxy server and the target web server is still maintained, and the web server needs to continue to accept and process data. An efficient http flood attack should continuously send http requests for different resources and pages, and request resources that cannot be cached as much as possible (such as keyword search. User-related information, etc.)如今，情势变了，她教的时候，侧重点也不同了，难怪香荽会挑出这点来说话。他挣扎着说完，苍白的脸色变得潮红，剧烈喘息不止。北大校草盛淮南偶然认识了同校平凡女生洛枳，两人一见如故，他渐渐被她吸引，但前女友的短信告诉他洛枳是破坏自己上一段感情的“元凶”。在追查真相的过程中，他却发现洛枳对自己的暗恋史。
