Static proxyFor example, before the program executes. The program ape is going to write a Proxy. Then compile, that is, before the program execution, the proxy class bytecode file has been generated (theproxy class file already exists). static agents, although in the enhancement of existing interface business functions have a great advantage, but a large number of such static agents, the system will make a large number of classes in the scale, difficult to maintain. and the Proxy class and the

Take out the ssh-agent, because as the company's springboard program is implemented, Ssh-agent will be used on a large scale or covertly. Understanding how it works helps me understand the deployment and operations involved, and how to safely drop applications.
