When it comes to proxy servers, the first thing we can think of is a dedicated Proxy server Web site that, in some cases, speeds up access to the Internet. In fact, in the need to access the external LAN, we can set up the agent, the number of visits to save the page in the cache, thereby "improve" the network speed.

The process is as follows: 1.

Protocol and proxy, protocol proxy ====================================== Protocols and Proxies ====================================== [Agreement] @ Protocol [Role of the Protocol]: Specifies the interface method to be implemented.

Design Mode-Proxy mode [Proxy Pattern] What is the proxy mode? I am very busy. I am not busy with you. If you want to contact me, please first look for my agent.

In the past two days, I watched a video about sogou's article crawling. I talked about ip

Concept:Static proxy: The source code is generated automatically by the programmer or a specific tool, and then compiled. Before the program runs, the. class file for the proxy classes already exists.Dynamic Agent: When the program is running, it is created dynamically using the reflection mechanism.The dynamic proxy of the JDK is very simple to use, when it has
