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.)　　经历了一番波折后，巴利安终于加入了十字军，继承了父亲的领地。当他来到耶路撒冷后，深深地被当地陌生而奇特的文化吸引，甚至爱上了公主希比拉（伊娃·格林饰）。然而当临死的耶路撒冷王请求他继承王位时，对权力纷争完全没有欲望的他断然拒绝。江成海为愚蠢的世人默哀了一分钟后，就对旁边一个高高瘦瘦的青年，说道：徐涛，你知道这首诗算什么样的水准？非常高的水准。少女们闪闪发光的青春日记。在北去的途中，张家小女儿香荽遭流寇掳走。
