[Lua] "Hello, world!" from Lua file?

[Shohreh]

Hello

Now that I have a working Nginx with the ngx_lua module, I'd like to start
learning how to write web scripts.

The following page doesn't have a basic sample:
http://wiki.nginx.org/HttpLuaModule

So I used the following...
http://yichunzhang.wordpress.com/2010/05/18/a-simple-ngx_lua-example-for-the-future/
... to edit nginx.conf and write a basic hello.lua file:

================ nginx.conf
...
    server {
        listen       12345;
        server_name  localhost;

        location / {
            root   html;
            index  index.html index.htm;
            content_by_lua_file hello.lua;
        }
...
================ html/hello.lua
print("Hello, world!")
================ 

But when I call http://192.168.0.10:12345/hello.lua, Chrome downloads the
file instead of displaying the output.

What should I do?

Thank you.
