HTTP

From Saferpedia

Hypertext Transfer Protocol - HTTP is the foundation of data communication for the World Wide Web. It is a networking protocol for distributed, collaborative, hypermedia information systems.

HTTP works as a request-response protocol in the client-server model. In HTTP, the web browser is the client, while an application running on a computer hosting a web site is the server. HTTP also defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page.

HTTP Resources are identified and located on the network by Uniform Resource Identifiers (URI) or Uniform Resource Locators (URL) using the http or https URI schemes. URI and the Hypertext Markup Language (HTML), form a system of inter-linked resources, called hypertext documents, on the Internet, that led to the establishment of the World Wide Web in 1990 by English physicist Tim Berners-Lee.

The original version of HTTP (HTTP/1.0) was revised in HTTP/1.1. HTTP/1.0 uses a separate connection to the same server for every request-response transaction, while HTTP/1.1 can reuse a connection multiple times, to download, for instance, images for a just delivered page. Hence HTTP/1.1 communications experience less latency as the establishment of TCP connections presents considerable overhead.

The HTTP protocol is a stateless protocol, which means that the connection between the browser and the server is lost once the transaction ends.
