Randall Hauch commented on DNA-309:
-----------------------------------

Another interesting blog from Roy Fielding, entitled "It's okay to use POST": http://roy.gbiv.com/untangled/2009/it-is-okay-to-use-post

Reminder, it is appropriate to use PUT when _replacing_ a resource, since PUT really requires a whole definition of the resource.  POST, on the other hand, specifies that the server accept the enclosed entity as a _subordinate_ of the resource with the supplied URI (e.g., POST a file under a directory with URI, or POST a property or set of properties under a node, or POST a child under a parent node).  This is different from PUT, which means that the enclosed entity be stored under the supplied URI.

Recall that GET and HEAD (identical to GET except that the server may not return a message body in the response) are "safe" methods in that they imply the client only asked for a retrieval, and they should not have the significance of any action other than a retrieval.  This doesn't mean that the server won't change its state; instead, it means that the client did not ask for side effects and therefore should not be accountable for them.

Also, PUT, POST and DELETE are idempotent, meaning multiple invocations do not change the result.  The OPTIONS and TRACE methods are also idempotent.

BTW, it is not clear to me what effect that same-name-siblings have on resource URIs.
