Abstract：   Let's start off this part by defining the term web application. We've all seen regular client-side applications, but what exactly is a web application? Loosely, it can be defined as an application running on a server a user accesses through a thin, general-purpose client. Today, the most common client is a web browser on a PC or workstation, but other kinds of clients are rapidly joining the party, such as wireless PDAs, cell phones, and other specialized devices.
   The lofty goal here is to access all the information and services you need from any type of device that happens to be in front of you. This means that the same simple client program must be able to talk to many different server applications, and the applications must be able to work with many different types of clients. To satisfy this need, the protocol of how a client and a server talk to each other must be defined in detail. That's exactly what the HyperText Transport Protocol (HTTP) is for.

摘要：让我们从定义Web应用程序开始。我们都看到过一般的客户端应用软件，但怎么样才是一个真正的Web应用程序？然而，它可以被定义为一个用于用户接入的运行在服务器上的程序，通过一个简单，一般用途的客户。今天，最常见的客户端是一种运行在pc机上的网页浏览器或工作站系统，但其他类型的用户正在迅速加入，如无线PDA ，手机，和其他专门设备。    最崇高目标是从你面前的任何类型的设备上获得你所要的信息和服务。这意味着同样的简单客户端程序必须能够与许多不同的服务器应用通话，以及应用程序必须能够适用于许多不同类型的客户。为了满足这一需要，必须制定详细的客户端和服务器相互通信的协义。这正是超文本传输协议（ HTTP ）的目的。
