title: Joomla trailing slash on categories
body: <p>I would like to know how to add a trailing <code>slash</code> to <code>joomla</code> categories, but have no extension on articles.</p>
  
  <p>Example, i want- <code>xxx.com/category1/ and xxx.com/category1/article</code></p>
  
  <p>Currently google sees- <code>xxx.com/category1/ and xxx.com/category1</code> as duplicate content.</p>
