Hello,

I'm a newbie to nginx and lua.Trying to write a module which should be able intercept a incoming request.

Lets say, actual request is intended to go to server A.I have to make a rest call to another server B before and after sending it to A. Have seen echo_location in nginx-echo-module which is trying to register a callback to a subrequest which works for me.But came across Lua concepts.Which one should I prefer in terms of effeciency? plain nginx running subrequests or lua-resty.what are the pros and cons of using them.

Thank you.

lua-resty-* libraries based on cosockets are the future. Subrequests
have many complications and limitations but fine for simple usage.
