The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems. It is a generic, stateless, protocol which can be used for many tasks beyond its use for hypertext, such as name servers and distributed object management systems, through extension of its request methods, error codes and headers. A feature of HTTP is the typing and negotiation of data representation, allowing systems to be built independently of the data being transferred.
超文本传输协议是一个为分布式的、协作的、超媒体信息系统制定的应用程序级协议 。它是通用的、无状态的协议，除了作超文本还有许多用途，如通过它的请求方法扩展，错误代码和头部，用作名字服务器和分布式对象管理系统。HTTP 的一个特性是数据表现的生成（typing）和协商，允许独立地建立数据传输系统。
HTTP has been in use by the World-Wide Web global information initiative since 1990. This specification defines the protocol referred to as "HTTP/1.1", and is an update to RFC 2068
