Too Long; Didn't Read
Tim Berners-Lee's proposal to build a hypertext system over the Internet was published in 1991. The first version of the World Wide Web was called the Mesh, but it was later renamed the WorldWideWeb in 1990. The protocol used in those early phases was very simple, later dubbed HTTP/0.9, and sometimes as the one-line protocol. In November 1996, an informational document describing the common practices has been published, RFC 1945. This is the definition of HTTP/1.0 and it is notable that, in the narrow sense of the term, it isn't an official standard.
