Launching reflective attacks requires finding a large number of transmitters on the Internet. Some kinds of reflective attacks are not difficult to implement. For example, for ACK reflective attacks, only servers with open TCP ports on the Internet need to be found, and the existence of such servers on the Internet is very extensive.赵文华不知道为什么，惹到了干爹。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.)杨长帆也不耽搁，冲兵士道，几位兵哥，有擦布么？老兵在箱子里翻了翻，还真找到一块油布，赶紧递给杨长帆。当兽医小哥哥想要买醉的时候遇到了一个暖心的调酒师，他们到底有发生关系吗？这个情人节有我陪伴你！这部真实的纪录片系列调查的案件中，被判谋杀罪的人声称他们的供词是被迫的，非自愿的虚假。
