Hi,

I needed to handle custom account subdomains with Rails and I wrote a  
simple rack middleware for that [http://github.com/drogus/rack-subdomain](http://github.com/drogus/rack-subdomain).  
It works by mapping any subdomain to given PATH. For example when user  
hits [drogus.example.org/account](http://drogus.example.org/account) and mapping is /users/:subdomain, it  
will map the request to [example.org/users/drogus/account](http://example.org/users/drogus/account)

I accomplished it with rack middleware, cause I wanted to have this  
mechanism also for Rails 2.x.

The thing is, I don’t want to duplicate stuff that’s already in  
router, so here is my question: is there any way to do such mapping  
with Rails 3 router? Or maybe a better way to handle custom account  
subdomains?

Cheers,

Peter
