That is possible (for stupid caches anyway, on purely technical grounds there should be no difference), it also looks much better to developers/users and is much, much easier to map/dispatch in most frameworks.

I was just talking about the restful part of the thing, your urls can look like this:

    http://example.org/?wubwub=9cec6c6faef8f7ccefe1bbf409368f1e3d0fa626

and still be part of a completely and perfectly restful service.
