Abstract
The Detail 2017
HTTP is a protocol with the lightness and speed necessary for a distributedcollaborative hypermedia information system. It is a generic statelessobject-oriented protocol, which may be used for many similar tasks such asname servers, and distributed object-oriented systems, by extending the commands,or 'methods', used. A feature if HTTP is the negotiation of data representation,allowing systems to be built independently of the development of new advancedrepresentations.
Note: This specification
This HTTP protocol is an upgrade on the original protocol as implementedin the earliest WWW releases. It is back-compatible with that more limitedprotocol.
This specification includes the following parts:
The following notes form recommended practice not part of the specification:
Purpose
When many sources of networked information are available to a reader, andwhen a discipline of reference between different sources exists, it is possibleto rapidly follow references between units of information which are providedat different remote locations. As response times should ideally be of theorder of 100ms in, for example, a hypertext jump, this requires a fast,stateless, information retrieval protocol.
Practical information systems require more functionality than simple retrieval,including search, front-end update and annotation. This protocol allows anopen-ended set of methods to be used. It builds on the discipline of referenceprovided by the Universal Resource Identifier (URI) as a name (URN, RFCxxxx)or address (URL, RFCxxxx) allows the object of the method to be specified.
Reference is made to the Multipurpose Internet Mail Extensions (MIME, RFC1341)which are used to allow objects to be transmitted in an open variety ofrepresentations.

On the internet, the communication takes place over a TCP/IP connection.This does not preclude this protocol being implemented over any other protocolon the internet or other networks. In these cases, the mapping of the HTTPrequest and response structures onto the transport data units of the protocolin question is outside the scope of this specification. It should not howeverbe at all complicated.
The protocol is basically stateless, a transaction consisting of
- Connection
- The establishment of a connection by the client to the server - when using TCP/IP port 80 is the well-known port, but other non-reserverd ports may be specified in the URL;
- Request
- The sending, by the client, of a request message to the server;
- Response
- The sending, by the server, of a response to the client;
- Close
- The closing of the connection by either both parties.
The format of the request and response parts is defined in this specification.Whilst header information defined in this specification is sent in ISO Latin-1character set in CRLF terminated lines, object transmission in binary ispossible.
Character sets
In all cases in HTTP where RFC822 characters are allowed, these may be extendedto use the full ISO Latin 1 character set. 8-bit transmission is always used.
