Splunk web redirect to FQDN?

I was looking around and maybe my googling is the best today, but I cannot seem to find a way to redirect the Splunk webserver. Basically our customers can access our Splunk servers with either the short name: https://splunkit:8000 Or the FQDN https://splunkit.mydomain.com:8000 My question is how do I get the Splunk webserver to redirect the short name to the FQDN? We are getting dedicated certs for the Splunk web interface and need customer's to access the FQDN for the certs to be valid. Any help or docs would be awesome thanks. -ed
