I have a website whose url is subdomain.example.com but I want users to use a different url to access it, example.com/subdomain. Just to add a bit of context, the two domains are on two separate servers, on different technologies, so I cannot put them on the same server. I know I can do redirect from one to the other but for marketing reasons end users cannot see the redirected url in the address bar but always the one they typed.
Is this possible? How to implement it?
