HTTP
HTTP (HyperTextTransfer Protocol) is a protocol used to transfer documents in the World Wide Web (WWW). This protocol is a lightweight, not generic and generic protocol that various types of documents can use. The HTTP development is coordinated by the World Wide Web Consortium (W3C) and the Internet Engineering Task Force (IETF) working group, working in the publication of a series of RFCs, the most famous RFC 2616, which describes HTTP / 1,1, HTTP versions commonly used today . HTTP is a request / answer protocol between client and server. An HTTP client, such as a web browser, usually initiates a request by establishing a TCP / IP connection to a specific port on a remote host (usually port 80). A listening diport HTTP server waits for the client to send a request code, such as "GET / HTTP / 1.1" (which will request the specified page), followed by a MIME message that has some header information that explains aspects of the request, followed by the body of certain data. Some headers are also freely written or not, while others (such as the host) are required by the HTTP / 1.1 protocol. Upon receiving the request code (and the message, if any), the server sends back the answer code, such as "200 OK", and a requested message, or an error message or other message.
History
The HTTP protocol was first used in the WWW in 1990. At that time the protocol used HTTP version 0.9. Version 0.9 is a raw document transfer protocol, meaning that document data is sent in accordance with the contents of the document regardless of the type of document. Then in 1996 the HTTP protocol was fixed to HTTP version 1.0. This change to accommodate the types of documents to be sent along with the encoding used in the delivery of document data. In accordance with the development of internet infrastructure then in 1999 issued HTTP version 1.1 to accommodate proxy, cache and persistent connection.
