i've installed the Request Routing plugin from that URL, but it does not seem to work on my application. the :requirements still does not have any effect. i can get the subdomain name with the SubdomainAsAccountKey plugin, but the subdomain routing can't work.
In the new version of Rails you need to use :conditions rather than :requirements
Also, request routing just specifies a requirement for routing. EG. you can say things like only use these routes if the subdomain is not admin or whatever so it might not actually be the answer to your problem but in this case it looks like it will work.
Cheers,
