Rack::HTTPCat

Adds an easter-egg link to a status cat in the headers of your Rack application.

Add to your Gemfile:

gem 'rack-http_cat'

And then execute:

$ bundle install

Or install it globally as:

$ gem install rack-http_cat

require 'rack/http_cat' and use Rack::HTTPCat in your config.ru (or whatever your application's entry point is).

You should see something like HTTP-Cat: https://http.cat/200 in the headers of a successful page load.

Without configuration Rack will handle 500 errors outside of your app and inside Rack itself, so you won't see a cat in your headers.
