I have the domain custom.com which I am trying to point to site.example.com which in turn points to example.com/site.

I currently have this in my Virtual Host:

ServerAlias *
VirtualDocumentRoot /var/www/html/%1

I have tried creating a CNAME record for custom.com which points to site.example.com, however for some reason it points to the root site example.com.

How could I allow users to directly point custom domains to subdomains of my site? What would have to be done to my Virtual Host/which records would be required?

Subdomains actually work as intended to since they point to the directories containing the same name. However, any custom domains pointed to any subdomain just points to the root site rather than pointing to the subdomain.

I would appreciate any help with this.

Thank you!

You are kind of on the right track as you do want the DNS for custom.com and site.example.com to point to the same host which is example.com. However DNS (CNAME) does not take the URI into consideration. This is why custom.com ends up being directed to example.com and not example.com/site.

To accomplish what you are looking for is to add some rewrite rule that change your custom.com domain to either site.example.com or to custom.com/site

Be careful and take into consideration on mapping your domains to not create redirect loops or to many redirects.
