What happened?

There is an issue with the 404 process where if you append anything to the address of internal pages, instead of showing a 404 page, it displays the parent page.

For example, this address:

dnnsoftware.com/about

is a valid address, but:

dnnsoftware.com/about/404404404

should give an error, yet it shows the same "about" page.

This issue exists on all pages.

Steps to reproduce?

1. Go to a page
2. add a random querystring to url
3. you see the parent page instead of 404 error page
