bozohttpd and lua, getting input from user

[coypu%SDF.ORG@localhost]

Trying to get GET/POST info.

I feel like I've tried all the examples I could find, and they all fail
with an error like:
failed to execute script /var/www/hello.lua: /var/www/hello.lua:70:attempt to index a nil value (global 'httpd')

Where that is httpd.register_handler(...)

What would be a valid way to get any input from a user using bozo&httpd?

Thanks.
