Overview

This simple Rack endpoint that serves as the default 'failure' mechanism for OmniAuth. If a strategy fails for any reason this endpoint will be invoked. The default behavior is to redirect to /auth/failure except in the case of a development RACK_ENV, in which case an exception will be raised.
