A WEB server is also called an HTTP server, which communicates with the client through the HTTP protocol. This client usually refers to a

I. Introduction
In the first article, we constructed the POP3 client user interface, the general goal of this series of articles. To create the basic visual structure of the mail

Alibaba at the beginning, just like ordinary Web site, through the front-end HTTP traffic in the completion of the database query, call, and then feedback back to the data. When the site becomes very big, can not be the same as in the past, only through a single system can complete a number of business functions, we need to split the system, service is the only way, the Java container was
responsible for the implementation of platform-based upper-level applications.For example, a Web site using Application Server WebLogic as a technology-supported platform, the server's provider (BEA) will not be responsible for the construction of specific site content. and application implementation platform (such as

All the DOM principles I 've been discussing so far will be used in this tutorial to create a dom-based dynamic web page that can work (although a little simple. If you don't know anything, you can stop and review the previous two articles at any time before returning.Starting with a sample

According to Extreme experts, there are actually three types of software for devices that are used to implement content recognition: A device built on a PC platform, a layer-3 Switch with a general CPU, and a network processor-
very complex Serializablethe object. Additionally, session synchronization increases the overhead that can affect server performance.On the other hand, stateless server-side components are less complex and easy to design, write, and distribute across load-balanced servers. A stateless service not only performs better, but also transfers most of the state maintenance responsibilities to the client application. In a REST-

The purpose of HTML writing is not to provide a structure or page appearance, but to better present the content. Therefore, before writing HTML, you must consider which semantic elements should be used for this content.
Appropriate HTML is ideal for cross-browser processing. After obt

, you also have an order execution program for the management of actual goods delivery. These two programs come from different software vendors. After a new order comes in, the Order login program needs to notify the order execution program to send the goods. By adding a web service to the order execution program, the order execution program can expose the "addorder" function. In this way, every time a new

to another server. In particular, the Load Balancer server supports two or more application servers and uses the allocation algorithm to forward requests to different servers. The simplest method of load balancing is rotation round robin, and each new request is sent to the next server in the list. Other methods of replication equalization include sending requests to the server with the fewest active connections. NGINX Plus has the ability to assign
