Not even remotely true.

REST is what it is in practice, not what some guy originally proposed as REST, in the same way modern words are not their etymology in Latin or Greek.

And in practice it's a re-invention of RPC, similar to XML-RPC, over HTTP and JSON, but with less rigor.

Kind of like any big C program has an ad-hoc implementation of half of Common Lisp thing.

>REST only involves HTTP conventions to the extent that one decides to use it over HTTP, and only because HTTP involves (obviously) HTTP conventions.

Ok, then you should have no issue with not using HTTP conventions and just use HTTP for transport.
