Country code as X- Header

Take a look at the following wiki article on the whereis command:

All modern F5 BIG-IPs come loaded with a "Geo-IP" database, primarily used for GTM geo-loadbalancing functions, but that is also accessible using the above command.

 

Thanks, so all I would need to know is how to set an X-header based on this

whereis  country

variable.

The HTTP::header insert method will do that for you, and the name of the header is arbitrary. Example:

when HTTP_REQUEST {
    HTTP::header insert "X-Country" [whereis [IP::client_addr] country]
}
