The template method pattern consists of two parts, The first part is the abstract parent class, The second part is the subclass of concrete implementation. Generally, the abstract parent class encapsulates the algorithm framework of the subclass, including implementing some common methods and encapsulating the execution sequence of all methods in the subclass. The subclass can inherit the parent class and rewrite the methods of the parent class in the subclass, thus realizing its own business logic.17.

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.)
