class Locomotive::Steam::Middlewares::PageNotFound
When rendering the page, the developer can stop it at anytime by raising an PageNotFoundException
exception. Instead of the page, the 404 not found page will be rendered.
This is particularly helpful with the dynamic routing feature to avoid duplicated page content (different urls, same HTTP 200 code but same blank page).
