I'm trying to replicate the traffic that one specific nginx server receives to two servers. The goal is not to load-balance, but to replay the same input on all nginx servers.
An example: Nginx receives a HTTP POST. I want to send this same POST to other servers.
** UPDATE **
The situation is easy and non-complex. I just need to resend the POST data (or GET or any request data) to another server IP (it also running a nginx instance). Just it.
USER -> POST DATA -> NGINX INSTANCE ----REDIRECT ---> SERVER 1 AND SERVER 2
