I want to create an record where
https://dev75.key.pre-prd.com/
get Route traffic to
https://api.key.pre-prd.com/service2
is it possible to create record with the path at the end?
Amazon Route 53 is a Domain Name Service (DNS).
Basically, a DNS server translates a domain name (example.com) into an IP address. So, when you type example.com into a web browser, your computer uses DNS to convert it into an IP address, then establishes a connection with a computer on that IP address.
This is similar to how your phone has a list of Contacts. You select a contact by their name, and the phone calls their telephone number.
DNS only refers to the name at the start of a URL (after http:// or https://) but before the first slash. This is the Domain Name. Anything after the domain name is sent to the recipient computer to tell it what page to retrieve. Thus, it is not possible to create a DNS Name that includes a path.
In your situation, you would need a web server listening on https://dev75.key.pre-prd.com/ that forwards the requests to https://api.key.pre-prd.com/service2. This cannot be done with DNS alone.
