If you`re using some kind of CMS, usually its normal that each URL works with or without trailing slash, e.g. these URLs would be the same:

After a bit of reading I chose to remove the slash from my celica site, because I`m using Drupal CMS that removes trailing slashes for new content and I don`t really want to hack the CMS plugins. To alter the URLs, you need to edit .htaccess file at the root directory of your website ( http://example.org/.htaccess )
Add this code to your .htaccess file to remove trailing slashes:
