Hi,
I have begun the process for the recommended first party cookie implementation using CNAME entries. Those are in place and Adobe has purchased the certificates. However, I'm wondering how this implementation will work correctly in test environments. For example, I test my implementation on www.mywebsites.test however the CNAME is setup with the domain smetrics.mywebsites.com so the first party cookies would not work because the domains are different, correct?
Is there a recommended way to implement this for non-production environments?
