Question

Which browser support REST completely? Means Get,Post,PUT and DELETE method?

I understood the rails way to understand PUT and DELETE is \"_method\" hidden variable

Answer 1

PUT and DELETE are just specifications, and are not implemented by any browser and web server.

So donot design RESTful web service with support for PUT or DELETE if you are sending request.
