　　7. Hail Britpop!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.)尹旭感慨不已。上衣是仿制男儿的箭袖，袖口和腰身都收得窄窄的，看去很是简便俏丽。　　命运作弄，让他们各奔东西，走向截然不同的人生，爱又将他们紧紧拉在一起，可时过境迁，物是人非，爱恨纠葛
