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 |
To be in context of this module for instance creation POST on
|
32 |
/2/instances is legitim while PUT would be not, due to it does create a
|
33 |
new entity and not just replace /2/instances with it.
|
34 |
|
35 |
So when adding new methods, if they are operating on the URI entity itself,
|
36 |
PUT should be prefered over POST.
