Enrich requests with geolocation
Difficulty level: Beginner
Objective
This challenge requires you to add headers to requests as they flow through Fastly, on the way to the backend. In this scenario, the backend server is configured to return different responses depending on the country in which the end user is located.
Add code that appends a client-geo-country header to the request and sets the value to the two-character ISO country code of the end user's location.
