33 PUT or POST?
34 ============
35
36 According to RFC2616 the main difference between PUT and POST is that
37 POST can create new resources but PUT can only create the resource the
38 URI was pointing to on the PUT request.
39
40 In the context of this module POST on ``/2/instances`` to change an existing
41 entity is legitimate, while PUT would not be. PUT creates a new entity (e.g. a
42 new instance) with a name specified in the request.
43
44 Quoting from RFC2616, section 9.6::
45
46 The fundamental difference between the POST and PUT requests is reflected in
47 the different meaning of the Request-URI. The URI in a POST request
48 identifies the resource that will handle the enclosed entity. That resource
49 might be a data-accepting process, a gateway to some other protocol, or a
50 separate entity that accepts annotations. In contrast, the URI in a PUT
51 request identifies the entity enclosed with the request -- the user agent
52 knows what URI is intended and the server MUST NOT attempt to apply the
53 request to some other resource. If the server desires that the request be
54 applied to a different URI, it MUST send a 301 (Moved Permanently) response;
55 the user agent MAY then make its own decision regarding whether or not to
56 redirect the request.
57
58 So when adding new methods, if they are operating on the URI entity itself,
59 PUT should be prefered over POST.
