http的jar包

超文本传输协议（HTTP，HyperText Transfer Protocol)是互联网上应用最为广泛的一种网络协议。所有的WWW文件都必须遵守这个标准。设计HTTP最初的目的是为了提供一种发布和接收HTML页面的方法。1960年美国人Ted Nelson构思了一种通过计算机处理文本信息的方法，并称之为超文本（hypertext）,这成为了HTTP超文本传输协议标准架构的发展根基。Ted Nelson组织协调万维网协会（World Wide Web Consortium）和互联网工程工作小组（Internet Engineering Task Force ）共同合作研究，最终发布了一系列的RFC，其中著名的RFC 2616定义了HTTP 1.1。
