Why is a slash added to the end of the url?

Question

htaccess

Hello, can you please explain why a slash is added to the end of the url?
I have htaccess file which contains code

RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_URI} !^/userimages/
RewriteRule .* index.php

And also the index.php file, in which, depending on the request, this or that page is connected.
All urls are opened without adding a slash, except for one.
And due to the fact that a slash is added there, all fonts and styles on the page fly off.
How to remove this slash at the end of the url?

Answer 1

If, after adding a slash, all fonts and styles on the page disappear, then you need to specify the path to the files from the root of the site. Those. instead of "style.css" put "/style.css". Or explicitly specify the base address for all relative links <base href="http://site.ru/"> htmlbook.ru/html/base
In the Apache settings, DirectorySlash is usually enabled and existing directories are redirected with a slash. Disable this behavior by adding DirectorySlash Offto htaccess.
