You are operating under basic misconceptions.
Let me clarify:
1. HTTP GET on an RFC 2396 URI returns an "entity" NOT a "resource"
2.An entity is a representation of a resource
(let's forget the "data" scheme for the moment until we understand the
Don't take my words as authoritative, rather let's actually read the
RFC 2396: Uniform Resource Identifiers: http://www.ietf.org/rfc/rfc2616.txt
see definitions of the terms "resource" and "entity"
The GET method means retrieve whatever information (in the form of an
entity) is identified by the Request-URI. If the Request-URI refers
to a data-producing process, it is the produced data which shall be
returned as the entity in the response and not the source text of the
process, unless that text happens to be the output of the process.
This discussion started in the context of the "REST" Architecture as
described in Fielding, R. 2000
It would be helpful to read the relevent documents because there is really
no point in arguing what is "logical" when we are defining our basic terms
in a different fashion.
