The not_found plugin adds a
not_found class method which sets a block that is called whenever a 404 response with an empty body would be returned. The usual use case for this is the desire for nice error pages if the page is not found.
You can provide the block with the plugin call:
plugin :not_found do "Where did it go?" end
Or later via a separate call to
plugin :not_found not_found do "Where did it go?" end
Before not_found is called, any existing headers on the response will be cleared. So if you want to be sure the headers are set even in a not_found block, you need to reset them in the not_found block.
This plugin is now a wrapper around the
status_handler plugin and still exists mainly for backward compatibility.
