This is an improved version of the hello word Nginx module found at http://blog.zhuzhaoyuan.com/2009/08/creating-a-hello-world-nginx-module/ This module also accepts a value to the module directive and validates its value as well as prints it, instead of printing static "Hello World"

The sample configuration can look like

server {
        listen 8080;
    server_name localhost;

    location / {
             hello 'Hello World';
    }
 }
