How do I route by domain / subdomain in rails

Question

I looked at subdomain-fu and it looks pretty easy to route all non-www and non-'' subdomain requests to a single controller.

But I also, need to send all external domains that are CNAME'd to my domain to the same controller. I have done a lot of searching and I can't find anything.

Summarized, if it is a subdomain on my domain it goes to Catchall controller, if it is any other domain than my domain, it goes to the same Catchall controller.

I am going nuts on this, any help would be appreciated.

Answer 1

You should check out the request_routing plugin. It allows you to easily route request by: subdomain, domain, method, port, remote_ip, content_type, protocol, etc.
