4.1 GetPackage Sequence
The following sequence occurs between a client and a server during a GetPackage request.
The client sends a GetPackage request.
If the server requires the client to be authenticated, the server and client 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 "200 OK" HTTP response along with the response payload as described in section 3.1.
The client closes the HTTP connection to the server.
