I like the distinction in the CGI documents on hoohoo between HTTP
headers (which the CGI program generates and are sent via the server
directly to the client) and _server_directives_, which are interpreted
by the server and may or may not be sent untouched to the client.
I like to think of a mapping between server directives (from the CGI)
and HTTP headers (from the server); this mapping may be a unity
transform but need not be.
Keeping this distinction also allows a spec to say that CGI programs
should output server directives before HTTP headers.
