It is a generic, stateless, object-oriented protocol which can be used for many tasks, such as name servers and distributed object management systems, through extension of its request methods (commands). 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. This specification reflects preferred usage of the protocol referred to as 'HTTP/1.0', and is compatible with the most commonly used HTTP server and client programs implemented prior to November 1994.");
