Hi Michael,
You should be able to load the file *(if the list of zones is large enough
and warrants a file)* or initialize array of subzones *(if there are few
zones you want to test)* once, when the process starts and loads the Lua
script. Loading the file on every request would definitely become

recursor, but probably does not matter in that case.
Does the file gets loaded for every request with io.open and could this become
