Write short note on HTTP.

HTTP (Hypertext Transfer Protocol) is the set ot rules for transferring hypertext, like text, graphic, image, sound, video etc., on World Wide Web.

It is an application-level protocol with the lightness and speed necessary for distributed, collaborative, hypermedia information systems. It is a generic, stateless, object-oriented protocol. A feature of HTTP is the typing of data representation, allowing systems to be built independently of the data being transferred.

HTTP is also used as a generic protocol for communication between user agents and proxies/gateways to other Internet protocols. The HTTP protocol consists of two fairly distinct items : the set of requests from browsers to servers and the set of responses going back to the other way.
