One of the great things about Drupal is its huge community of developers. Drupal.org hosts many, many modules to extend and enhance your website or application. Most people know about popular modules such as CCK, Views2, Panels, and XML Sitemap. But there are some really great modules that fly under the radar as well.
1. Secure Site
When developing a website, you occasionally show the client progress. Depending on your setup, you use either an internal development address, or a subdomain like development.company.com to make it accessible outside for clients. What if you want to hide it away from prying eyes or search engines? There have been times when curious people have stumbled across sites I’ve worked on by trying subdomains, but this little module will put a stop to that. Secure Site uses HTTP authentication and prompts the user for a username and password before proceeding. It can also be used to secure RSS feeds.
