Hi all,

I would like to route a request to a specific domain  
(‘request\_routing’ plugin installed) to controllers living in a  
subfolder for that domain like this:

[http://www.mydomain.com/home/index](http://www.mydomain.com/home/index)  
:controller =\> ‘mydomain/home’, :action =\> ‘index’

I would like to use a general route like ‘/:controller/:action’

Is it possible to somehow access the string matched by :controller,  
extend it and use the extended string as the controller, like the  
following?

# mydomain routes

map.with\_options :requirements =\> { :domain =\> /^mydomain/ } do |  
mydomain|  
mydomain.connect ‘:controller/:action’, :controller =\> “mydomain/  
#{controller\_match}”  
end

Thanks for any hint!
