How to pass a request from Nginx to two backends?

Question

Nginx

We need to check the statistics system that we have in order not to wedge into the main code, I want to get the same request as the system itself. How can I make nginx pass the request to two scripts at once?

Answer 1

Perhaps Goreplay will suit you . It can listen to traffic on a port, like tcpdump, and forward it either to a file for later analysis or repetition, or to another backend.
