Examples:
/something/foo --> show /something
/something/foo/bar --> show /something
/something/foo/bar/baz --> show /something
I'll parse the URL with JS.
Also, in my machine the route is localhost/websites/MyWebsite/something so ideally it should also work for my machine (or if it's not possible, I need to .htaccess one for the server and one for my machine)
Well nobody answered so after a lot of testing this worked for me:
RewriteRule ^something/(.+)$ something.php
In my case it was a php file
