Pointig a domain

Hi

I have a question to ask you to see if I can do something with your plugin. I can get the PRO plugin if needed.

Let’s assume that the website http://www.second-domain.com is a wordpress site developed in 3 languages (main: Italian, then English and Spanish) using WPML and other plugins (e.g. Yoast SEO, Contact Form 7, etc.).

In practice, I would like a domain (www.first-domain.com) to point to another WordPress site/domain (www.second-domain.com), but in the English language version that is the URL http://www.second-domain.com/?lang=en.

As a consequence of this pointing, I want that when a user enters the URL http://www.first-domain.com in the browser, the browser retains and show in the address bar the URL http://www.first-domain.com (without or with /?lang=en), but the contents are those of http://www.second-domain.com/?lang=en in English.

Furthermore, if a user then navigates to the various pages of http://www.first-domain.com or changes language, he/she will always see the contents of http://www.second-domain.com, even for the Italian and Spanish languages, but the URL must be http://www.first-domain.com (without or with /?lang=es).

Is it possible to do this with your plugin?

Clearly we have access to the domains and can change all the DNS records.

Thank you very much for your cooperation.
