This object holds the host name that gets used in the redirected URL instead of the server's raw IP address, when this server is selected while the Director is operating in HTTP redirector mode. Because clients see this name, not the server's IP, in the redirect, an admin sets this to match a valid DNS record and any TLS certificate configured on the server, or clients could hit certificate mismatch warnings or broken links after being redirected. If a server's TLS certificate is issued for east-mirror.example.com, this object for that server should be set to exactly that hostname so redirected clients land on a URL matching the certificate rather than triggering a browser security warning.
