2，https The main idea of HTTPS is to create a secure channel over an unsecure network.The trust inherent in HTTPS is based on major certificate authorities which come pre-installed in browser software.HTTPS内核已经预安装在各种浏览器中。
3, HTTP client is Web Browser.HTTP client就是浏览器。
4,Representational State Transfer (REST) is a style of software architecture for distributed hypermedia systems such as the World Wide Web. Conforming to the REST constraints is referred to as being ‘RESTful’.REST是标准，符合此标准的被称为RESTful。
