The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative,
hypermedia information systems. It is a generic, stateless, protocol which can be used for many tasks
beyond its use for hypertext, such as name servers and distributed object management systems,
through extension of its request methods, error codes and headers [47]. A feature of HTTP is the
typing and negotiation of data representation, allowing systems to be built independently of the
data being transferred. HTTP has been in use by the World-Wide Web global information initiative
since 1990.
