User Variable in Rails view filename

By default, Rails can find views with the format, language, and language of the template in the file name (so I can create index.de.json.erb)

Can I add another custom parameter to the view file name?

I would like to transfer the current subdomain, so it http://foo.example.com/will display index.foo.html.erb, and it http://bar.example.com/will display index.bar.html.erb(both of them with a index.html.erbbackup).
