How to make the subdomain subdomain.domain.com available at domain.com/subdomain?

Question

CMS

Hello.
The essence of the problem is that it is not possible for a Joomla site at domain.com/subdomain to behave exactly the same as on subdomain.domain.com.
Everything is fine on subdomain.domain.com, relative links do not work on the second option.
Thank you.

Answer 1

Do not work relative - use absolute

Answer 2

You need to configure the web server itself, little depends on the CMS.
