It mainly refers to constructing XSS cross-site vulnerability web pages or looking for cross-site vulnerability web pages other than non-target machines. For example, when we want to penetrate a site, we construct a web page with cross-site vulnerabilities, then construct cross-site statements, and deceive the administrator of the target server to open it by combining other technologies, such as social engineering, etc.清末民初，国家命运多舛之际，民族积弱危难之秋。北京城里的一场骚乱拉开了故事的序幕。袁世凯在北京就任大总统，但却不愿到南方就职，纵使手下蓄意扰乱治安，一天深夜里，一群群的乱兵开始抢劫店铺，因为藏有大量财宝，典当行业首当其冲。眼看着乱兵就要来了，可是唇齿相依的德恒当铺和聚源当铺却各有各的烦心事：乱世之秋，聚源当铺的大掌柜尤光耀二房太太瑞芸香分娩在即，而尤光耀却不知道去了哪里，一直不能生育的大太太何溪诗更是伙同姘头巡官于万全，将瑞芸香产下的孩子故意当作死婴遗弃；而何于二人更有着不可告人的勾当；被仍在垃圾堆上的孩子却误打误撞被尤光耀和瑞芸香共同的师兄，德恒当铺的大掌柜吴流芳收留。德恒当铺更是乱成了一锅粥，当铺被乱兵乱民所抢，不仅仅丢失了财物，而当铺行业的命根子账本也不幸遗失，而此时为了救儿子命的谭凤翔找上门来，要典当一颗举世无双的祖传宝石；神秘的古董商人夏德海也恰好漏夜拜访，送上一份惊世骇俗的珠宝清单，跟随夏德海接踵而至的却是乱兵乱民，土匪地痞；当铺的‘正账’李先生混乱中被乱兵枪杀；而吴流芳的农师傅老铁是那种让你觉得他生来就应该是师傅的人！徐文长也就此丧失了基本的逻辑判断，为什么杨长帆这个人可以指山为金？不过从地势上来看，这样的谷地高地悬殊，地形奇葩，也的确是产金矿的地方。SYN flooding attacks can attack with fewer packets than ordinary brute-force DoS attacks that only send a large number of packets to the target network. However, this requires some understanding of the server's operating system, such as how much backlog queue space it allocates and how long it will keep the TCB in the SYN-RECIEVED state before timeout and discarding the TCB. For example, an attacker can send a certain number of SYN packets that are exactly the size of the backlog queue, and their cycles are just the time when the TCB is recycled, thus making the server permanently unavailable.她一点一点地和排练缔结了合作关系，但却被卷入了以他为目标的组织之间的斗争中。而且那场战斗和她的过去也有关系。
