Rack::Maintenance is a simple Rack middleware to detect the existence of a maintenance.html page and display that instead of incoming requests.
sudo gem install rack-maintenance
# config/environment.rb config.middleware.use 'Rack::Maintenance', :file => Rails.root.join('public', 'maintenance.html'), :env => 'MAINTENANCE'
If :env is specified, all requests will be shown the maintenance page if the environment variable is set.
If :env is not specified, the maintenance page will be shown if it exists.
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with Rakefile or VERSION (do that in a separate commit if you want a local version)
Send me a pull request. Bonus points for topic branches.
