How do I redirect users to an error 404 page if they enter a trailing "/" (or anything after a "/"), after the page name?

Question

On an Apache/Linux Server, how do I redirect users to an error 404 page if they enter a trailing "/" (or anything after a "/") after the page name?

For example, this URL should direct to an error page:

http://www.example.com/contactus.php/someextrastuffhere

Whereas, this URL should not:

http://www.example.com/contactus.php?name=john+smith&[email protected]

However, the latter URL breaks my site.

Can this be solved with a simple .htaccess directive?

Answer 1

You can have this rule as your very first rule in your root .htaccess:

RewriteRule ^.+?\.(php|html?)/ - [L,R=404,NC]

This will send any /file.php/foo request to 404 whereas http://www.example.com/contactus.php?name=john+smith&[email protected] won't be impacted.
