The Hypertext Transfer Protocol, or HTTP, is the application-level protocol that governs how a web browser requests a resource such as a page or an image from a server and how the server returns that resource, forming the basic communication rule of the World Wide Web. British computer scientist Tim Berners-Lee designed the first version of HTTP in 1989 and 1990 at the CERN research laboratory alongside HTML and the first web browser, as part of the same project that created the web. The protocol has since been revised several times, most notably HTTP/1.1 in 1997, and is now most often used in its encrypted HTTPS form, which layers HTTP over Transport Layer Security to protect data in transit.

What does it mean that HTTP is stateless?
Each HTTP request can be understood on its own, without reference to earlier requests.
HTTP is defined as a stateless protocol. In the words of the current HTTP specification, that means each request message's semantics can be understood in isolation, so the meaning of a request does not depend on earlier messages. Websites that need to remember a visitor between requests, such as a login or a shopping cart, have to add that memory on top of the protocol themselves.
