Do you have a way to end my URLs with a slash please?

Hello,
After reading the guide and search on Google, I have trouble understanding this sentence :
«Do not use leading/trailing slashes»

you can find this sentence at this address : codeIgniter route (v2.2)

If I understand this code is not valid :

Code:

$route['myFolderWithSlash/'] = ‘exempleController’;

In this case, how to get a URL that ends with a slash, without modifying the value below :

Code:

$config['url_suffix'] = '/';

I often use routes that does not require a slash, exemple :

Code:

$route['exemple.html'] = 'anotherController';

my urls like "^ index\. php" are automatic redirect to a 404 error (404_override).

Do you have a way to end my URLs with a slash please?
is it risky to use routes as described either for security or compatibility with future versions?

I did my best to translate this topic in English, sorry if you have trouble reading it.

My first question is why do you need this? Answering this will help us figure out a solution I'm sure.

Your English is fine.
