Chaining bouncer inside access_by_lua_block

Hi everyone! I'm setting up an OpenResty bouncer but I need it chain it before a different module (which is a custom DDoS protection script) so that the module that follows after the bouncer is the final one that completes the request. My

access_by_lua_block

access_by_lua_block

is roughly as follows:

-- snip

local bouncer = require "lua/bouncer"
bouncer.bounce()

-- DDoS protection script is called here and must be called last

-- snip

local bouncer = require "lua/bouncer"
bouncer.bounce()

-- DDoS protection script is called here and must be called last

The contents of

bouncer

bouncer

are as follows:

local function bounce() {
  local cs = require("crowdsec")
  cs.Allow(remote_addr)
}

local function bounce() {
  local cs = require("crowdsec")
  cs.Allow(remote_addr)
}

In a configuration like this, the bouncer processes the request so the visitor reaches the page without DDoS check ever being triggered.

My question is -- is it possible to intercept/override the behavior of the bouncer to allow the request to continue? Thanks in advance!
