I think you can use the subrequest API for this. For example,
https://github.com/openresty/lua-nginx-module#ngxlocationcapture
But be careful when your response bodies are huge because this API
function captures the full response body of the subrequest in memory
(and in Lua space).

This is because of the limitations in NGINX output filter's current
implementation and there's nothing we can do on our side without
redesign that part in the NGINX core.
