Overview

HTTPError help you to create your own 404, 500 and/or 501 response

To create a custom 404 reponse, create a fonction HTTPError.r404 in your application :

module Capcode
  class HTTPError
    def r404(f)
      "#{f} not found :("
    end
  end
end

the rXXX method can also receive a second optional parameter corresponding of the header’s Hash :

module Capcode
  class HTTPError
    def r404(f, h)
      h['Content-Type'] = 'text/plain'
      "You are here ---> X (#{f} point)"
    end
  end
end

Do the same (r500, r501, r403) to customize 500, 501, 403 errors
