Heilongjiang Province突然，他双掌一击——张经若胜必死。茶，沉吟片刻之后，说道：此事算得上是一个你情我愿的合作，为了同一个目标而奋斗，结束之后各取所需而已。Reflective attacks typically use protocols that do not require authentication or handshake, The reflection attack needs to forge the source ip address of the requested data into the ip address of the target. If the protocol used requires authentication or handshake, the authentication or handshake process cannot be completed and the next attack cannot be carried out. Therefore, most reflection attacks are carried out by network services based on udp protocol.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.)三天三夜，足够全北京看到王世贞的下场后，严嵩才终于出门，充满怜悯地看着王世贞。木子与莱恩青梅竹马一起长大，就在一次郊游的途中他们意外发生了车祸。再次醒来的时候，二人被关进了小黑屋，费劲周折终于从小黑屋走了出来。可意外再次发生了，他们迷路了，小小的医院竟然走不出去了，恐怖的事情就此发生了……
