Introduction

Web framework is a software framework that is designed to support the development of web applications like dynamic website, web service APIs. It frees developer from lower layer details and provide tools to accelerate the development. A framework usually correspond to one or more languages and types of Database.

Except for standard libraries, web framework often provide libraries for frequently used functions in web applications and hide low level details to the developer. It also has all required protocols well implemented, i.e. HTTP(s) and all supporting protocols. Except the standard library, most web framework will include libraries for frequently used functions and modules by default, like: URL Encoding, HTTP Request header parsing, URL mapping, session module and Database module.

In addition, Template, Caching, Load balance, URL Fetch, DoS Protection, Frontend Channel, Mail, Open Authorization, DOM management, XMPP are also commonly seen features in most modern web framework.

Web application process

Most web applications are based on HTTP(s) protocol, where client and server uses Request-Response method to exchange information. In a typical round, client sends information encoded into a HTTP request header, server will respond with a HTML page, Json or XML data. The response is usually real-time generated based on the request.

Usually server only respond to requests and is not able to start a connection to client, unless certain hack like Javascript Channel is used.
