Description

Gili:

Can the authors officially weigh in on the meaning of "idempotent"

with response to response codes? Do idempotent methods have to return the same response code in the face of multiple invocations? Or are they allowed to return different response codes so long as the state is not modified by subsequent requests? See http://stackoverflow.com/q/741192/14731 for the discussion that fueled this question.

PS: It would be nice if the spec officially clarified this point as

I've seen it brought up again and again in different discussions.
