We have a webapp and companies can customize the look and feel. Now we'd like them to be able to make the app part of their existing website by allowing them custom subdomains.
Our app : www.ourapp.example Their site : www.somecompany.example Their subdomain : ourapp.somecompany.example (shows ourapp.example)
Note: www.somecompany.example is an existing website, so we don't want to replace it with our site.
I tried adding a CNAME "ourapp" which points to
www.ourapp.example, but it gives me a "Resource not found" error, probably because IIS does not know what to do with the incoming URL?
