 SubdomainFu can also work within Rails' routing for subdomain-specific routes. For instance, if you only wanted your administrative tools available in the "admin" subdomain you could add this to your routes.rb file:
 
-    map.with_options :conditions => {:subdomain => 'admin} do |admin|
+    map.with_options :conditions => {:subdomain => 'admin'} do |admin|
       admin.resources :posts
       admin.resources :users
     end

+In addition to specifying a string, you could also specify <tt>false</tt> to
+require no subdomain (this includes mirrors that you've set up such as www)
+or a regular expression to match a range of subdomains.
