You might be misunderstanding what this does. It doesn't rewrite your URL and add ".html".
Instead it rewrites any generated URLs.
eg:
Code:
echo site_url('test/xx');
// produces "http://yourdomain/test/xx.html"
It also strips off the ".html" when reading the request. for eaxmple if you have pagination it will still understand ""http://yourdomain/test/xx/page/4.html""
Hope that makes sense
