rack-vhost
Rack middleware to dispatch to an application via host header.
Install gem:
gem install rack-vhost
or in Gemfile:
source :rubygems
gem 'rack-vhost'
Example config.ru:
require 'rack/vhost'
class Router
def call(env)
[200, { 'Content-Type' => 'text/plain' }, 'Router app']
end
end
class APIApp
def call(env)
[200, { 'Content-Type' => 'text/plain' }, 'API app']
end
end
class MainApp
def call(env)
[200, { 'Content-Type' => 'text/plain' }, 'Main app']
end
end
# This should come after all other middleware since it passes directly to the app
use Rack::Vhost, :vhost => '^api', :app => APIApp.new
use Rack::Vhost, :vhost => 'www.philcolabs.com', :app => MainApp.new
run Router.new
