Your reasoning is sound, and I agree with it.  Indeed, I had been thinking
of files.

A few questions:

 1) Do you need to define "behaves exactly like"?  or 'environment at the

  In particular, do you mean that the response to GET must be
octet-for-octet identical to that from origin?  If so, would you mind
stating that explicitly?  But also, if so, what would happen to a resource
that used a server-side include that e.g. was position dependent?  So
perhaps 'octet-for-octet' is too strong.

 2) Presumably, the new resource is allowed to respond differently in so

Are there any other allowed differences?

 3) What about the etag?  Must it change?  Is is allowed to stay the same,
if the entity body as returned by GET remains octet-for-octet the same?
