I have a multi-tenant app on Heroku where each tenant has a portal (micro-site) that lives in a sub-directory (e.g.
http://www.example.com/portals/foo-bar). My domain is hosted by GoDaddy and I want each tenant to be able to create a subdomain on their site for their portal to live in. I'm trying to create my own subdomain to test the process, but I can't figure out how to link a subdomain to a subdirectory on GoDaddy. I would presume that the process is pretty similar across domain registrars, but I'm not sure.
If I try creating an A record or a CNAME, it will only accept an IP address. I could create a simple redirect, but I want my user to stay on the subdomain as they interact with the portal, rather than simply be redirected from
Is this possible, and if so, how?
