Geolocation with more than one country

Using a switch:

when HTTP_REQUEST {
    switch -glob [whereis [IP::client_addr]] {
        "*US*" -
        "*CA*" -
        "*UK*" {
            HTTP::redirect "http://www.example1.com/"
        }
        
        "*MX*" -
        "*CR*" {
            HTTP::redirect "http://www.example2.com/"
        }
        
        default {
            HTTP::redirect "http://www.example3.com/"
        }
    }
}

or a datagroup:

ltm data-group internal country-redirect {
    records {
        CA {
            data http://www.example1.com/
        }
        CR {
            data http://www.example2.com/
        }
        MX {
            data http://www.example2.com/
        }
        UK {
            data http://www.example1.com/
        }
        US {
            data http://www.example1.com/
        }
    }
    type string
}

along with:

when HTTP_REQUEST {
    set redir [class match -value -- [whereis [IP::client_addr]] contains country-redirect]
    if { $redir ne "" } {
        HTTP::redirect $redir
    }
    else {
        HTTP::redirect "http://default.example.com/"
    }
}
