DDOS attacks mainly occur in the network layer. Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.

State mode is one of the implementations of state machines, but in a "classless" language like javascript, there is no stipulation that state objects must be created from classes. On the other hand, Java Script can use delegate technology very conveniently without having one object hold another in advance. The following state machine chooses to delegate the request directly to a literal object through the Function.prototype.call method

Many older plants are wind-borne plants, such as conifers, but insect-borne pollination, which appeared later, is not necessarily more advanced than wind-borne pollination. Nettles are a good example. The nectar of nettles has a good smell, so it seems that nettles, like their ancestors, want to attract insects to pollinate, but surprisingly, nettles' first choice is to pollinate through the wind.

The meaning of cache agent is to cache the first run time, and when running the same again, it will be taken directly from the cache. The advantage of this is to avoid repeating the operation function once. If the operation is very complicated and consumes the performance, then using cache objects can improve the performance. We can first understand a simple cache column, which is the common addition and multiplication operations on the Internet. The code is as follows:
