## The idea behind the example

React Server Side rendering is very costly and takes a lot of server's CPU power for that. One of the best solutions for this problem is cache already rendered pages.
That's what this example demonstrate.

This app uses Next's [custom server and routing](https://github.com/zeit/next.js#custom-server-and-routing) mode. It also uses [express](https://expressjs.com/) to handle routing and page serving.
