It is made clear by implication throughout RFC 1945 that 'simple-request'
and 'simple-response' refer to HTTP/0.9. It is not explicitly stated,
but there are several specific cases supporting this interpretation.
RFC 1945, section 3.1:
The version of an HTTP message is indicated by an HTTP-Version field
in the first line of the message. If the protocol version is not
specified, the recipient must assume that the message is in the
simple HTTP/0.9 format.
Contrariwise, if there *is* a version, the request is *not* in
the simple HTTP/0.9 format. Arguable, I suppose.. but:
Section 4.1:
HTTP messages consist of requests from client to server and responses
from server to client.
HTTP-message = Simple-Request ; HTTP/0.9 messages
| Simple-Response
| Full-Request ; HTTP/1.0 messages
| Full-Response
Section 5:
A request message from a client to a server includes, within the
first line of that message, the method to be applied to the resource,
the identifier of the resource, and the protocol version in use. For
backwards compatibility with the more limited HTTP/0.9 protocol,
there are two valid formats for an HTTP request:
Request = Simple-Request | Full-Request
Simple-Request = "GET" SP Request-URI CRLF
Full-Request = Request-Line ; Section 5.1
*( General-Header ; Section 4.3
| Request-Header ; Section 5.2
| Entity-Header ) ; Section 7.1
CRLF
[ Entity-Body ] ; Section 7.2
If an HTTP/1.0 server receives a Simple-Request, it must respond with
an HTTP/0.9 Simple-Response.
Section 6:
A Simple-Response should only be sent in response to an HTTP/0.9
Simple-Request or if the server only supports the more limited
HTTP/0.9 protocol.
