The full form of HTTP is Hypertext Transfer Protocol. The full name of the standard application-level protocol for file exchange on the World Wide Web is HTTP or HyperText Transfer Protocol. The TCP/IP protocol and, later, the QUIC protocol are built on top of HTTP. Web servers respond to file requests via an HTTP service after being sent by web browsers, which are HTTP clients. Tim Berners-Lee, a contributor to the 1.0 standard, first suggested HTTP in 1989.
HTTP/1.0 (sent in 1996) was “stateless”: rather than handling all similar requests through a single connection between a particular client and server, each new request from a client formed a new connection. Persistent connections, client browser decompression of HTML files, and numerous domain names sharing the same IP address are all features of HTTP/1.1, which was introduced in 1997.

The 2015 introduction of HTTP/2, a binary protocol in which binary values were utilised instead of plaintext as in earlier versions, was created to address issues with delayed page loading.
Although it had not yet been released in its complete form as of early 2022, HTTP/3 relies on the quicker QUIC protocol rather than TCP and is supported by the majority of browsers. Many websites started using HTTPS (Secure HTTP) in the 2010s. This protocol was created in 1994 by Netscape Communications Corporation and adds the SSL (Secure Sockets Layer) protocol to HTTP to add an encryption layer between browsers and servers.
