Module rlib2

Remote API version 2 baserlib.library.

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.

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.

So when adding new methods, if they are operating on the URI entity itself, PUT should be prefered over POST.
