How to remove duplicate slashes in Laravel 4.2 url and put a closing slash on categories?

Question

Apache HTTP Server

During the development of the project on Laravel 4.2, I discovered that a URL like example.com//////news is available , that is, you can substitute an infinite number of slashes and get page duplicates. How to fix?
And how to make it so that at the end of the URL for a category (if it does not have a .html extension) a closing slash is delivered, indicating that articles are contained there?
Thank you.

RewriteCond %{REQUEST_URI} ^(.*)/{2,}(.*)$
