Q:

Does Azure front door actively replicate its cache?

Does the AFD cache push / replicate out to additional POP's, once an initial request to a single POP has completed? I cant find any documentation on the AFD documentation in relation to this. 
Ultimately what I want to know is:
If an initial request occurs from EU, served by the EU POP (after pull though from origin server); then 1h later an identical request occurs from the US, is this request a 'cache hit' in the US POP, or a miss with a read through?

A:

The first request by the any POP will not be cached. As per your example, the request sent form US will be a MISS and any subsequent request will be cached in that POP server.
