Does idempotence include the response codes?

Hi,

     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.

Thank you,
Gili
