By default and by design, when a requested short URL is not found, YOURLS redirects to the site root with a "302 temporary redirect" header.
From the source:
yourls_redirect( YOURLS_SITE, 302 ); // no 404 to tell browser this might change,
// and also to not pollute logs
This plugin outputs a default "404 not found
" error page instead.
- In
/user/plugins
, create a new folder named404-if-not-found
. - Drop these files in that directory.
- Go to the Plugins administration page (eg.
http://sho.rt/admin/plugins.php
) and activate the plugin. - Have fun!
Do whatever the hell you want with this.
