- PUT or POST?
- ============
+PUT or POST?
+============
- According to RFC2616 the main difference between PUT and POST is that
- POST can create new resources but PUT can only create the resource the
- URI was pointing to on the PUT request.
+According to RFC2616 the main difference between PUT and POST is that
+POST can create new resources but PUT can only create the resource the
+URI was pointing to on the PUT request.
- To be in context of this module for instance creation POST on
- /2/instances is legitim while PUT would be not, due to it does create a
- new entity and not just replace /2/instances with it.
+In the context of this module POST on ``/2/instances`` to change an existing
+entity is legitimate, while PUT would not be. PUT creates a new entity (e.g. a
+new instance) with a name specified in the request.
- So when adding new methods, if they are operating on the URI entity itself,
- PUT should be prefered over POST.
+Quoting from RFC2616, section 9.6::
+
+ The fundamental difference between the POST and PUT requests is reflected in
+ the different meaning of the Request-URI. The URI in a POST request
+ identifies the resource that will handle the enclosed entity. That resource
+ might be a data-accepting process, a gateway to some other protocol, or a
+ separate entity that accepts annotations. In contrast, the URI in a PUT
+ request identifies the entity enclosed with the request -- the user agent
+ knows what URI is intended and the server MUST NOT attempt to apply the
+ request to some other resource. If the server desires that the request be
+ applied to a different URI, it MUST send a 301 (Moved Permanently) response;
+ the user agent MAY then make its own decision regarding whether or not to
+ redirect the request.
+
+So when adding new methods, if they are operating on the URI entity itself,
+PUT should be prefered over POST.
