The usual proxy server, which is the forward proxy, is used only for proxy connection requests from the internal network to the Internet, and the client must specify a proxy server and send HTTP requests that would otherwise be sent directly to the Web server to the proxy se

An agent is a person or an agency acting on behalf of another person or another institution. In some cases, a customer does not want to or cannot directly refer to an object, and the proxy object can act as a mediator before the client and the target object.The proxy mode provides a proxy object to an object, and the

This blog post, we mainly in the form of class diagram and code to learn about static agents and dynamic agents, focusing on the advantages and disadvantages of each.DefinedProxy pattern is the structural pattern of an object, which provides a proxy object to an object and controls the reference to the original object by the proxy object.ClassificationStatic agents and dynamic proxiesStatic proxyStatic
Java dynamic proxy classes can be divided into two types.Static agents: Created by a programmer or by a specific tool, the source code is automatically generated, and then compiled. Before the program runs, the. class file for the proxy class already exists.Dynamic Agent: When the program is running, it is created dynamically by using the reflection mechanism.First, we have a Java Dynamic

Java Dynamic proxy ModeProxy: a role represents another role to implement some specific functions.For example, the relationship between producers, middlemen, and customersCustomers who buy products do not directly deal with producers, nor do they know how the products are produced. Customers only deal with middlemen, and middlemen can carry some packaging on the products, provide some after-sales services.

DNS queries to negatively cache failed requests. Squid supports SSL and access control. Because of the use of ICP (lightweight Internet Cache Protocol), Squid can implement a layered proxy array to maximize bandwidth savings.
Squid is composed of a major service program squid, a DNS query program dnsserver, several programs that rewrite requests and perform authentication, and several management tools. After Squid is started, it can derive a specifie
