Apache: Clean URLs with FallbackResource
I only just now learned about the FallbackResource directive in Apache, which is a very basic alternative to the Rewrite module, eg. when you want clean URLs.
Apache will then use the
index.php file, unless the file or directory exists - so all your images, css and js files will still work.
Read the full documentation here: https://httpd.apache.org/docs/2.4/mod/mod_dir.html
This is a very simple and easy solution for "rewriting", without needing the rewrite module, but of course won't always be enough.
