How to get the users country via CDN header?

with Episerver cloud, the backend code simply reads the clients country code from the CF-IPCountry header which cloudflare puts on to each request automatically. 

What do you get with AEM cloud?  it has flastly, which i understand has similar functionality to cloudflare?

Basically, we need block/route requests based on which country they are from, and do logic in our AEM app.

We wrote a simple servlet to dump the headers, deployed it to the cloud env, and then when we hit the servlet we dont see the x-aem-client-country header.  to fix we need to add it to clientheaders.any
