webMethods 10.1 How to use Interceptor technology in REST


I am aware that with webMethods SOAP EndPoints we can develop the services which works as Interceptors.
We can register the Provider with “pub.soap.handler:registerWmProvider”.
Also develop the services which can be used as handlers for Pre and Post of any web Service call.

This is used to register the handlers services which can be called for every request, before and after processing for any request.

I am looking for the similar implementation on the REST side.
Need help how we can develop the Before and After wrapper services, without affecting the actual REST services code.
