Passing request header to response headers via Transform Rules

[pantelis1]

I am trying to pass the CF-IPCountry header to my response headers.

I then go to Rules → Transform Rules → HTTP Response Header Modification rule

None of the following solutions work (CF throws an error - unrecognised input). What is the correct way to go about it?

It sounds like you might want to use ip.geoip.country?

Some good references:
