When attempting to perform a urlfetch DELETE call, it seems the payload is explicitly NOT added. From urlfetch.py:
if payload and method in (POST, PUT, PATCH): request.set_payload(payload) This makes it impossible to work with an API provided by our vendor. Is there any particular reason that a payload cannot be added to a DELETE urlfetch? j -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
