Hypertext Transfer Protocol (HTTP)

HTTP follows a request/response model. A client sends an HTTP request to the server providing information about the request method being used, the requested Uniform Resource Identifier (URI), the protocol version being used, various other header information and often other details, such as details from a form completed on the Web browser. The server responds by returning an HTTP response consisting of a status line, including a success or error code, and other header information followed by a the HyperText Markup Language (HTML) code for the static page requested by the client.
