Re: Redirecting part of a URL
SteveD1979 First I will be changing domain.com to example.com. I'm not understanding why the client would be entering application.something.gtm.example.com in the first place. Typically the way DNS is configured is you would have the following.
*** DNS at auth NS for example.com ***
application.something.datacenter.example.com 300 IN CNAME application.something.gtm.example.com
*** DNS on GTM for gtm record ***
application.something.gtm.example.com 300 IN A 1.1.1.1
application.something.gtm.example.com 300 IN A 1.1.1.2
Then the client would connect to either IP depending on what the GTM responded with while still maintaining the FQDN application.something.datacenter.example.com. Typically you wouldn't want to narrow down the FQDNs to be a specific datacenter name because that allows people to aquire more information about your infrastructure than they should.
