Patching FancyIndex Module NginX

NginX sebenarnya sudah mempunyai module default untuk directory index, namun, ada module 3rd juga yang ditulis oleh Adrian Perez de Castro yang bikin directory index ini lebih menarik. Kalau dari dokumentasi yang ditulis oleh bang Adrian ini, kita juga bisa membuat desain template directory index sendiri.

Demo : http://www.antituhan.com/dev/nginx-modules/
How to install module :

./configure --add-module=../nginx-fancyindex-0.1_beta5
