多年来，万维网已经迅速地从静态文档的交付系统发展到今天的分布式Web应用程序编程的流行平台。Stuttard和Pinto(2011)认为，万维网以前仅由包含静态文档的信息存储库组成，信息以一种方式从服务器流向浏览器。如今，大多数网站都是高度实用的应用程序，依赖于服务器和浏览器之间的双向信息流。Joshi, Aref, Ghafoor和Spafford(2001)将web应用程序描述为“三层架构”，它由“web客户端、网络服务器和一组数据库支持的后端信息系统”组成。(38页)。Chlipala(2015)声称，如今具有丰富功能的web应用程序必须“为文档结构生成HTML”;CSS文档格式;JavaScript，一种用于客户端交互的脚本语言;还有HTTP，一种用于在浏览器之间发送上述所有信息的协议。web应用程序的常见功能包括购物、社交网络、银行和交互信息等。

Over the years, the World Wide Web has rapidly evolved from a delivery system for static documents to a popular platform today for programming distributed web applications. According to Stuttard and Pinto (2011), the World Wide Web formerly consisted only of information repositories that contained static documents, and the information flowed in one way, from server to browser. Nowadays, most websites are highly functional applications counting on two-way flow of information between the server and browser . Joshi, Aref, Ghafoor and Spafford (2001) illustrate a web application as "a three-tier architecture" that consists of "a Web client, network servers, and a back-end information system supported by a suite of databases." (p. 38). Chlipala (2015) claims that a web application of rich functionality today must "generate HTML, for document structure; CSS, for document formatting; JavaScript, a scripting language for client-side interactivity; and HTTP, a protocol for sending all of the above and more, to and from browsers." Common functions of a web app include shopping, social networking, banking and interaction information, etc.
