module Repia
  ##
  # This class serves as a middleware to handle Method Not Allowed error
  # (which is not handled by show_exceptions for some reason).
  #
  # Code was excerpted from https://gist.github.com/viola/1243572 and was
  # modified to serve a JSON response.
  #
  # Add it after ActionDispatch::RequestId to keep the request ID in the
  # response headers.
