HTTP is a transactional protocol based on the client-server model: A HTTP client sends a request, the HTTP server answers back with a response. The HTTP transaction is done when the response was completely transmitted.
An HTTP request allows to perform a certain action on a web resource located somewhere on the World Wide Web. The action is defined by one of the HTTP methods the protocol specifies and the web resource is defined by the URI (Uniform Resource Identifier).
