Overview

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 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.
