I use Kleeja script to host files and noticed that certain files are downloaded many more times than the site's visit counter indicates. So I assume that the files are being leeched. The web server is Nginx. Just wondering how to block leeching.

There are a number of ways to accomplish this, including using .htaccess files to redirect based on referrer. For nginx, NginxHttpRewriteModule
