I tried working with lua but the speed was extremely slow, 0.17/0.16. I dont think lua is made for a web server, I think only PHP can do this kind of job unless someone professional with lua comes up with something.
This is what I had for garbage.lua
local Code = {}
for i = 1, 100 do
table.insert(Code, string.char(math.random(65, 90)))
print(Code[i])
end
