I currently redirect URL's using the code below within a .htaccess file.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^news/(.*)$ /news/page.php?ref=$1
This works perfectly and enables me to run a script within page.php to retrieve the correct article. The issue I have is that /news/ gets redirected to page.php, even though no article is specified within the url. How can I modify this code to avoid this. 
Currently as a quick fix I have put a condition at the beginning of the page.php file that checks if ref is set and if not then redirect to /news/index.php. This works because I have specified a file, index.php. I would like the url /news/ to resolve without index.php having to be specified.
