In Kapersky's DDoS Attack Report published in the second quarter of 2011, HTTP flood attack is the most common DDoS method, which is an example of application layer attack. The dominance of application layer attacks reflects that the rapidly evolving DDoS has broken away from the traditional direction of large traffic attacks.玉玺印记？差别自知？什么意思？众人尚有些疑惑，显然都还未反应过来。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.)　　在最艰难的时刻，一个名叫李保全（李晨饰）的男子出现在海灵眼前，这是个胸怀广阔的男人，他不计较海灵的过去，他不顾家里的种种反对，毅然走到海灵身边，用自己纯真的心，化开了海灵内心中的寒冰，让她终于愿意再次接受一颗能够理解自己，温暖自己的心。然而，两人的感情和命运却并非一帆风顺。
