Let's say I have a next js app and a page like this. nextapp.com/content3
So, what I want to achieve is that somehow map the domain name userdomain.com to my Nextjs page nextapp.com/content3.
So, In the end when someone enters userdomain.com in their browser my page i.e. nextapp.com/content3 should be rendered on it.
No redirects, I need to be on userdomain.com but use my Nextjs page content.
