This is not working for me
showing "nil" , I'm using rails 1.2.3 with mongrel server in dev mode.
My code looks like this in production/development :

in routes.rb

map.connect '', :controller => "account", :action => "login", :conditions => {:domain => "tokyo.com"}

in environment.rb

module ActionController
module Routing
class RouteSet
def extract_request_environment(request)
{ :method => request.method, :domain => request.domain}
end
end
class Route
alias_method :old_recognition_conditions, :recognition_conditions
def recognition_conditions
result = old_recognition_conditions
result << "conditions[:domain] === env[:domain]" if conditions[:domain]
result
end # def
end # class Route
end # module Routing
end # module ActionController


i registered subdomain name as "sub.tokyo.com" for domain "tokyo.com" to provide different templates based on request url.

in application.rb i used :

def check_domain
if request.domain == "tokyo.com"
return true
elsif request.subdomains.first == "sub"
return false
end
end

In development i configure /etc/hosts too
127.0.0.1 : localhost
127.0.0.1 : tokyo.com
127.0.0.1 : sub.tokyo.com

could you help me to fetch my sub domain
is return nil when puts request.subdomains.first

thanks
sri..
