PUT response

[Justin Makeig]

Dumb question: what's the appropriate response to a PUT request? When  
I implement Resource#put and nothing goes wrong I get a 200 status,  
but my Resource never visits its getRepresentation(Variant) method to  
build a response payload. Is this the expected behavior or have I  
wired something incorrectly? I can't tell what's supposed to happen  
from the spec <http://www.w3.org/Protocols/rfc2616/rfc2616- 
sec9.html#sec9.6>.
Any help would be much appreciated.
