list the request-response interaction

Answer 12

• An HTTP Client opens a connection and sends a request message to an HTTP server. Typically a request is either GET or POST.
• The server then returns a response message, usually containing the resource requested. Typically in XHTML, XML or JSON.
• After delivering the response, the server closes the connection, making the HTTP a stateless protocol. It doesn’t maintain any connection information between the transactions.
