How restful service identify which user calling which method And how to make restful service as stateful?

As restful service stateless, it don't maintain any interaction of user, so i want to know if multiple user accessing same restful service, then how restful service identify which user interact with which method ? and is it possible to make restful service as stateful ?

Solution

  • Which user:

    By using a shared secret (a line of chars), created on the server, and returned with every next request.

    It's "saved" in a cookie and returned by the client, using either a cookie or a HTTP(S) header.

    Which method:

    This depends on the framework you use. But eventually it comes down to mapping URI's to your methods.

    and is it possible to make restful service as stateful ?

    You can make stateful apps, then they are not restful. A restful app is stateless. That's the definition, so you can make stateful apps, but you can never create a stateful rest-app, as rest is stateless.
