Overview

Vienna::NotFound is a default endpoint not unlike Rack::NotFound. Initialize it with the path to a 404 page and its contents will be served. The difference is that if a 404 page doesn’t exist, a default response, ‘Not Found’ will be served.

Examples

run Vienna::NotFound.new('public/404.html')

run Vienna::NotFound.new # Always return 'Not Found'
