Hi Krishna
I am not sure if you have understood or I explained correctly.
My WordPress is hosted where you can access it using few domains and not only one “1 main domain and 2 other add-on domains on the virtual host”. I have two pages that are directly related to two of the other add-on domains. I like people when they access my WordPress site via the add-on domains to end up seeing the specified pages related and not the home page first.
