A DELETE request, if not resulting in an error, will always return HTTP status 200 and no body content, no matter if a queue with that name exists or not

There seem to be a number of views on the correct behaviour here in REST APIs, based somewhat on how one interprets the notion of idempotence.

See for example http://stackoverflow.com/questions/23486992/rest-api-proper-http-status-code-for-invalid-delete  and http://stackoverflow.com/questions/6439416/deleting-a-resource-using-http-delete 

http://www.restapitutorial.com/lessons/httpmethods.html suggests 404 for such a case, but also points mentions how 204 (empty body) and 200 (which maybe should return the representation of the deleted entity) can be used in the non failure case
