If you ask about argument between HAProxy configuration file and Lua
function, I assume than my documentation is incomplete.
"converters" and "sample-fetches" can have a maximum of 5 arguments.
All the arguments are strings. If HAProxy, the declaration is like this:
http-request redirect location %[lua.my_function(arg1, arg2, arg3)]
The Lua declaration is like this:
function my_function(txn, arg1, arg2, arg3)
-- do something
end
The "action" functions can not have arguments.
If you ask about the convention call in Lua, the official
documentation will be more precise than me.
