Application layer attacks use more sophisticated mechanisms to achieve hacker targets. Application layer attacks do not use traffic or sessions to flood the network, but slowly deplete resources on the application layer for specific applications/services. Application layer attacks are very effective at low traffic rates. From a protocol point of view, the traffic involved in the attacks may be legitimate. This makes application layer attacks more difficult to detect than other types of DDoS attacks. HTTP flood, DNS dictionary, Slowloris, and so on are examples of application layer attacks.新的一季里的人物将由第一季结局在乌鸦岭医院幸存下来的人出演,当他们出席在爆炸中牺牲的他们中的一员的葬礼时,就会为您揭晓.只是徐文长，他是再也得不到了。 他的大师兄——二十岁的少僧Jung-sim虽然住在寺院多年，但每对着一见钟情的女子，仍闯不过情关而动了色心，并且打算还俗。寺院的主持面对两名僧人，不知如何是好……Remember when I was working on the front end, That is, the first company that has just graduated, It is a company that does outsourcing projects. The company generally outsources Taobao activity pages and Tencent's game pages, We should have called it cutting the front end of the page at that time. Do some html and css work, So when I was doing Tencent's game page, Often help them make static pages, For example, put a few buttons on the page, We just helped Tencent games to fix the style according to the design draft. For example, the buttons on the page and so on, For example, how to operate the specified buttons, What happens when the button is clicked, We don't know, We don't know what their business is. Of course, what we know will definitely be a click event. We don't know exactly what business to deal with. Here we can use command mode to deal with it: after clicking the button, we must send requests to some objects responsible for specific behaviors, which are the recipients of the requests. However, at present we do not know what the receiver is or what the receiver will do. At this time, we can use command mode to eliminate the code coupling relationship between the sender and the receiver.The te finds that it is blocking page response information from the browser, Forward the information you don't need, Find the information you need, The corresponding information will also be loaded through the Forward page, The following figure shows BurpSuite's interception page: 2.2. BurpSuite Replay Attack 2.2. 1 Replay Attack Replay Attacks, also known as Replay Attacks, Replay Attacks or FreshnessAttacks, refers to the attacker sending a packet received by the destination host to deceive the system, which is mainly used in the identity authentication process and destroys the correctness of authentication. It is a type of attack that repeats an effective data transmission maliciously or fraudulently. The replay attack can be carried out by the initiator or by the enemy that intercepts and retransmits the data. Attackers use network monitoring or other means to steal authentication credentials and then re-send them to the authentication server. From this explanation, encryption can effectively prevent session hijacking, but it cannot prevent replay attacks. Replay attacks can occur during any network communication. Replay attack is one of the common attacks used by hackers in the computer world. Its written definition is abstract to people who do not know cryptography. However, through learning, we know that the best way to defend against replay attacks is timestamp. Simply speaking, what is timestamp, that is, the verification code that we need to enter when visiting some websites to log in, and replay attacks cannot cope with every time we log in.该剧是以真人真事改编的电视剧，讲述2003年的春天，中国香港经历了一场没有硝烟的战争， SARS（重症急性呼吸综合征）大规模在市区爆发。在这场战争之中，一班抗疫医护人员因为爱，丧失了宝贵的生命。其中一位医生在丈夫去世后自愿加入Dirty Team，最终也染上非典型肺炎而牺牲的故事。
