Rack::HerokuNoSuchApp

Rack middleware to prevent loading from *.heroku.com / *.herokuapp.com addresses by serving default Heroku 404 page for "App not found". Use in combination with custom domains.

Usage

require "rack/heroku/no-such-app"

use Rack::Heroku::NoSuchApp

Including this in the config.ru file of your Rack application will respond to requests for *.herokuapp.com (or redirected from *.heroku.com) with the following 404 page:

Heroku | No such app

There is no app configured at that hostname. Perhaps the app owner has renamed it, or you mistyped the URL.
