What is HTTP/1.1

reference : https://en.wikipedia.org/wiki/HTTP_301

Answer 1

HTTP 1.1 is the latest version of Hypertext Transfer Protocol (HTTP), the World Wide Web application protocol that runs on top of the Internet's TCP/IP suite of protocols. HTTP 1.1 provides faster delivery of Web pages than the original HTTP and reduces Web traffic. Developed by a committee of the Internet Engineering Task Force (IETF) that includes the Web's chief creator Tim Berners-Lee, HTTP 1.1 is supported by the latest Web servers and browsers.
