Arun,
The client is doing a GET, so there is not entity in the request (no payload), but there's an entity in the response. Thus,
1) aroundReadFrom called in client to process response entity
2) aroundWriteFrom called in server to generate response entity
To get both called on both sides you need a POST/PUT request that sends and entity and expects another entity back. Order should be:
aroundWriteFrom (client)
aroundReadFrom (server)
aroundWriteFrom (server)
aroundReadFrom (client)
