Nginx+Lua

Идея построить сайт/сервис на луа + nginx подогревала меня давно, т.к. должно получиться очень быстро. Понемногу раскрываю тему.

server
{
	listen 80;
	server_name blockbot;
	access_log  /var/log/nginx/blockbot.access.log;
	error_log   /var/log/nginx/blockbot.error.log info;

	client_max_body_size 1024m;

	location /
	{
	    lua_code_cache off;
	    set_by_lua_file         $suspicious     /home/artem/projects/blockbot/suspicious.lua;
	    if ($suspicious) {
	        content_by_lua_file /home/artem/projects/blockbot/captcha.lua;
	    }
