The Domain Pointing CNAME run into default web page CWP

Ok... i have lets say i have 2 domain.

1. ABC.com
2. DEF.com

On ABC.com i'm using ANOTHER SERVER, and DEF.com i'm using CWP.
than i create CNAME record "www".ABC.com to DEF.com

The problem is My ABC.com showing "Test Page CWP" not like FrontEnd DEF.com.

CNAME Following this PATCH "USR/APACHE/HTDOCS/Index.html".

Do you know how to handle it ?

Thank you

as for any other domain the same needs to be configured in the panel which will than add configuration to the webservers.
CNAME is a simple DNS record it doesn't handle webserver folder locations
