HTTP/2 (formerly HTTP/2.0), or Hypertext Transfer Protocol 2.0, is the next generation HTTP protocol. It was developed by the Internet Engineering Task Force (IETF) Hypertext Transfer Protocol Bis (httpbis) Working Group. This is the first update since http1.1 was released in 1999. HTTP 2.0 was first tested for interoperability in August 2013. HTTP 2.0 will only be used for https://URLs on the open Internet, while http://URLs will continue to use HTTP/1, with the aim of increasing the use of encryption on the open Internet to provide strong protection against active attacks. DANE RFC6698 allows domain name administrators to issue certificates themselves without going through a third-party CA.
