I have website providing restaurant menus for hundreds of restaurants,
currently I am providing subdomains for each restaurant such as restaurant1.my-website.com
but many customers request to use their own domains to show their menu, for that I would like to point (mirroring) their domains to my subdomains in my website such as
I was thinking to use CNAMEs in my hosting, but it will be a big list of CNAMEs and not sure if hosting service can handle that number of CNAMEs
is there any way to point their domains to my subdomains in the website ?
