jan 1, 1997 - HTTP/1.1

Description:

The Hypertext Transfer Protocol (HTTP) is an application layer protocol for distributed, collaborative, hypermedia information systems.[1] 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.
HTTP/1.1 was first documented in RFC 2068 in 1997, and as of 2021, it (plus older versions) is less popular (used by less than a third of websites; it's always a backup protocol) for web serving than its successors. That specification was obsoleted by RFC 2616 in 1999, which was likewise replaced by the RFC 7230 family of RFCs in 2014.
