Hypertext Transfer Protocol (HTTP)

A Stateless Search, Retrieve and Manipulation Protocol

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-reserved 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.
