It is possible to require our load balancer to provide a super proxy in a specific country.
Choosing the super proxy country can be done like this: servercountry-{country}.brd.superproxy.io. E.g. servercountry-gb.brd.superproxy.io
curl--proxy servercountry-gb.brd.superproxy.io:22225 --proxy-user brd-customer-<CUSTOMER_ID>-zone-<ZONE_NAME>:<ZONE_PASSWORD> "http://target.site"
