Introduction to Proxy mode and proxy Mode1. Introduction to Proxy Mode
The proxy mode is structured.
The proxy mode provides a proxy object for an object and controls the reference to the original object by the
A proxy is a common design pattern designed to provide a proxy for other objects to control access to an object. The proxy class is responsible for preprocessing messages for the delegate class, filtering messages and forwarding messages, and performing subsequent processing of the message after the class is executed. Before we talk about dynamic proxies, let's t
Understand and use design patterns, can cultivate our good object-oriented programming habits, at the same time in the practical application, can be a duck to the fun, enjoy.
Proxy is a more useful mode, and more varieties, applications cover small structure to the whole system of large structure, proxy is the meaning of proxy, we may have a
In the java design mode, the proxy mode is widely used. For example, when I write a web program and modify the request or response in the filter, the request does not have a set method, in this way, you need to use a new class to implement the HttpServletRequest interface, put the original request into the new class and call the original method for the corresponding method in the new class. Then, the server passes the request to the Servlet so that th
Virtual Agent Mode-virtual ProxyVirtual proxy mode defers the actual time required for object instantiation. If a proxy object can handle a real object before it needs to work, the real object is not needed for the moment.Pros: The advantage of this approach is that when the application starts, it accelerates application startup because it does not require all objects to be created and loaded.disadvantage:

When using an existing method, you need to improve or modify the original method. At this time, there are two ways to improve: modify the original method to adapt to the current use method, or use a "third party" method to call the original method, and control the results of the method. The first method obviously violates the principle of "open to extension and disable to modify", and modifications to the original method may blur and diversify the functions of the original class, the second meth

First, the server commonly used ports
Each host (hosts) on the Internet has a unique address (IP), but the same host may provide more than one service, such as the FTP service, the WWW service, and so on, so that each service occupies one port of that host.
The common ports used by proxy servers are:
HTTP Proxy: 80/8080/3128/8081/9080
Socks Agent: 1080
FTP Agent: 21
