  24  PUT or POST? 
  25  ============ 
  26   
  27  According to RFC2616 the main difference between PUT and POST is that 
  28  POST can create new resources but PUT can only create the resource the 
  29  URI was pointing to on the PUT request. 
  30   
  31  In the context of this module POST on ``/2/instances`` to change an existing 
  32  entity is legitimate, while PUT would not be. PUT creates a new entity (e.g. a 
  33  new instance) with a name specified in the request. 
  34   
  35  Quoting from RFC2616, section 9.6:: 
  36   
  37    The fundamental difference between the POST and PUT requests is reflected in 
  38    the different meaning of the Request-URI. The URI in a POST request 
  39    identifies the resource that will handle the enclosed entity. That resource 
  40    might be a data-accepting process, a gateway to some other protocol, or a 
  41    separate entity that accepts annotations. In contrast, the URI in a PUT 
  42    request identifies the entity enclosed with the request -- the user agent 
  43    knows what URI is intended and the server MUST NOT attempt to apply the 
  44    request to some other resource. If the server desires that the request be 
  45    applied to a different URI, it MUST send a 301 (Moved Permanently) response; 
  46    the user agent MAY then make its own decision regarding whether or not to 
  47    redirect the request. 
  48   
  49  So when adding new methods, if they are operating on the URI entity itself, 
  50  PUT should be prefered over POST.
