[01/12/2009] HTTPHTTP: HTTP is the usual abbreviation for Hypertext Transfer Protocol. Application-level protocol contains HTTP for collaborative, distributed, hypermedia information systems. It is used to retrieve inter-linked resources known as hypertext documents. World Wide Web Consortium and Internet Engineering Task Force coordinated its standard development. HTTP is a response/request standard in client-server computing. HTTP presumes reliable transport; any protocol that provides this guaranty can be used. Uniform Resource Identifiers (URIs) identify resources that are to be accessed by means of HTTP. For request/response transactions, Transmission Control Protocol (TCP) is established on a particular port. There are eight methods for the action on identified resource which are following:
HEAD, GET, POST, PUT, DELETE, TRACE, OPTIONS, CONNECT.
HTTP is the key in web design in terms of connectivity.
