Rack::WWWme is an easy way to automatically redirect root domain requests to use www, using Rack.
Rack::WWWme was created to solve a very simple problem. At Klubensapps we needed an in-house solution to redirect root domain requests to www. Thus we hacked together Rack::WWWme as an extremely simplistic solution. After we were done, we threw it up on Heroku with a couple line rackup file and everything magically worked. We've open-sourced Rack::WWWme, along with our rackup file (see "Usage" below), so that other cloud-friendly developers would finally have an easy way to redirect root domain requests to use www.
Using Rack::WWWme is simple! Just include gem 'rack-wwwme', :git => 'git://github.com/klubensapps/rack-wwwme.git' in your Gemfile. Then add the following line the your config.ru file after any run statements:
use Rack::WWWme
That's it! Enjoy the freedom of root domain to www redirection!
Our Experience: We've deployed Rack::WWWme to Heroku using the following rackup file, a Gemfile, and Heroku's custom domain functionality. Basically all we did was deploy an app containing the following rackup file (and a Gemfile, of course) to Heroku and then add the respective root domains to Heroku's that we wanted to redirect to use www.
Our config.ru file:
# Require Rack::WWWme
require 'rack/wwwme'
# Run failsafe response in case WWWme fails
run lambda { |env| [200, { 'Content-Type' => 'text/plain' }, ['Error: Server failed to redirect user. Please try typing "www." infront of the URL.'] ] }
# Run WWWme
use Rack::WWWme
