URL Handling

Good afternoon.
A problem of this kind, a space or % occurs periodically in the url, it is necessary to redirect to the 404 page if the % sign occurs in the url.
Thank you in advance.

Answer 1

RewriteCond %{THE_REQUEST} %
RewriteRule ^ - [R=404,L]

You can specify your own 404 error page in ErrorDocument 404
If you need to catch addresses with spaces.
RewriteRule \s - [R=404,L]
