How to redirect to /404?

Question

htaccess

There is a url mysite.ru/mylink, but the engine also shows this page if you add anything to the url, for example - mysite.ru/mylink/ololo /mylink is a specific url

Answer 1

Engines usually have a routing module that does this. And .htaccess only points to the entry point to index.php. Google the documentation for the engine or look for routing settings in the engine files
