Unlike HTTP/1.1 FTP does not tell which was the DNS name attempted, as
that information is lost SLB can not use that information to steer
traffic. Connecting with ftp to ftp.cisco.com, ftp-sj.cisco.com or
198.133.219.241 in above case would be equal.
Of course we can't determine where 198.133.219.241 will end up,
but where ever it will be, ftp-sj or ftp does not make difference.
