Htaccess: добавить/удалить косую черту в URL-адресе ⇐ Php

[Anonymous]

На моем веб-сайте используется сценарий -> сценарий обоев WSS. Я пытался принудительно удалить или добавить косую черту в конце моего URL-адреса, чтобы предотвратить дублирование контента, а также очистить мои URL-адреса.
Поэтому я представляю вам весь свой код .htaccess:
DirectoryIndex index.php
