Hypertext Transfer Protocol (HTTP)

An Hypertext Transfer Protocol (HTTP) is a communication protocol for distributed, collaborative, hypermedia information systems.

• Context:
  • It can define the behavior of HTTP Connections.
  • It can support an HTTP Request Method (for the delivery of HTTP request messages).
  • It can support an HTTP Response Method? (for the delivery of HTTP response messages).
  • It can be implemented into an HTTP-based Server, such as a web server.
  • …
• Counter-Example(s):
  • HTTP/1.1.
  • HTTP/2.
  • HTTP/3.
  • …
• Counter-Example(s):
  • a WebSocket Protocol.
  • a gRPC Protocol.

  • The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser.

    Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989. Development of early HTTP Requests for Comments (RFCs) was a coordinated effort by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), with work later moving to the IETF.

    HTTP/1.1 was first documented in in 1997. That specification was obsoleted by in 1999, which was likewise replaced by the family of RFCs in 2014.

    HTTP/2 is a more efficient expression of HTTP's semantics "on the wire", and was published in 2015; it is now supported by major web servers and browsers over Transport Layer Security (TLS) using an Application-Layer Protocol Negotiation (ALPN) extension where TLS 1.2 or newer is required. HTTP/3 is the proposed successor to HTTP/2, which is already in use on the web, using UDP instead of TCP for the underlying transport protocol. Like HTTP/2, it does not obsolete previous major versions of the protocol. Support for HTTP/3 was added to Cloudflare and Google Chrome in September 2019, and can be enabled in the stable versions of Chrome and Firefox.
