+more easy. Message exchanges have a \emph{Request} and \emph{Response} header.
+The \emph{Request} header means that the server is sending to the client. The
+\emph{Response} header means that the client is sending to the server. In some
+cases either the \emph{Request} or \emph{Response} is empty. This means that
+the message is not acknowledged or responded upon.
