If I try and access some random string in the URL of my rails app, such as /asdfasdifjasdfkj
then I am seeing a rails error message
Routing Error
No route matches "/asdfasdifjasdfkj" with {:method=>:get}
Even though I am in production mode. Clearly I don't want any real users to see this, and would prefer a 404 page. Anyone know whats going wrong and how I fix it?
