Let I have two domains named www.abc.example and www.xyz.example hosted in different servers.
I have a .htaccess file in the root directory of www.abc.example (i.e. www.abc.example/.htaccess)
What will be the .htaccess script if I want to load the contents of www.xyz.example when I request from www.abc.example.
As for example: If I browse www.abc.example/test then it will display the content of www.xyz.example/test and so on without changing the host url (i.e. www.abc.example) in browser's addressbar.
