nginx custom module multi process help

[de_nginx_noob]

If the external server that I'm getting the data from doesn't have a
relational database (and instead responds to udp requests), will I still be
able to cache multiple fields from one udp request using Lua so that I can
access them in the conf file later? Can you clarify what you mean by Lua
cache? Thank you for your help!
