4.4 SendStatusReport Sequence
The following sequence occurs between a client and a server during a SendStatusReport request.
The client sends a SendStatusReport request.
If the server requires the client to be authenticated, the server and client exchange access authentication HTTP headers as specified in [RFC2616] section 11.
If authentication is not required, or if authentication has succeeded, the server responds with a HTTP 200 (OK) response.
The client closes the TCP connection to the server.
The following figure shows a message sequence with a single SendStatusReport request.
