In part two we created a simple application with as single REST endpoint. The client can calls the endpoint and show the requested resource. The resource changes periodically to simulate real situations. Now it is time to go to the next level.

In part one we dicussed HTTP ETag mechanism. In this part we are going to implement an APS.NET core application that uses ETag.

As we all know, HTTP protocol mostly works based on the request and response mechanism. Each request and response force data to be transferred over network.
