# Two ENV variables control the 'gem' command:
#
#   GEM_HOME: the single path to a gem dir where gems are installed
#   GEM_PATH: a standard PATH to gem dirs where gems are found
#
# A gem directory is a directory that holds gems.  The 'gem' command will lay
# out and utilize the following structure:
#  
#   bin               # installed bin scripts
#   cache             # .gem files  ex: cache/gem_name.gem

Implement Routing for Subdomains

Rails 3.0 introduced support for routing constrained by subdomains.

A subdomain can be specified explicitly, like this:

match '/' => 'home#index', :constraints => { :subdomain => 'www' }
