The overwhelming majority of Web developments are built based on Web application of HTTP protocol. To analyze the server program based on the HTTP protocol and the process of interaction between the browser and server, a simple HTTP-based server program is taken as an example to describe how to use the theories of multi-threading and asynchronous operation, and the core section of HTTP-based server program is gradually resolved with Winsock programming. This method can achieve the purpose to avoid blocking the calling thread, and improve the responsiveness of a server program.%绝大多数的Web开发,都是构建在HTTP协议之上的Web应用.为了分析基于HTTP协议服务器程序以及测览器与服务器的交互过程,以一个简单的基于HTTP协议中服务器程序为实例,探讨怎样使用多线程与异步操作的理论,运用WinSock编程来逐步解析HTTP协议的服务器程序的核心部分,这样既可达到避免调用线程阻塞的目的,又可提高服务器程序的可响应性.
