advanced scripting capabilities. Only versions 5.3 and above are supported.
In order to enable Lua support, please specify "USE_LUA=1" on the command line.
Some systems provide this library under various names to avoid conflicts with
previous versions. By default, HAProxy looks for "lua5.3", "lua53", "lua". If
your system uses a different naming, you may need to set the library name in
the "LUA_LIB_NAME" variable.

If Lua is not provided on your system, it can be very simply built locally. It
can be downloaded from https://www.lua.org/, extracted and built, for example :
