Lua nginx example

[Fabio Martins]

Just installed nginx-lua + onion2web via luarocks 5.1

nginx.conf complains about
content_by_lua directive inside the server { tag:

nginx: [emerg] unknown directive "content_by_lua" nginx-lua-1.28.2
(installed)

Does anyone has example about running lua under nginx on openbsd? Including
nginx.conf?

Thanks.
