Repeat requests

Server NGINX
1

Hi

I am new to nginx.

Can i use nginx to repeat / duplicate incoming requests …? I
understand
that I can use nginx to load balance … but in my use case, i need to
duplicate the request. The incoming request should be routed to server0
AND
server1. Is it possible with nginx? Thank you for your help

Assuming such a thing were possible, what could you sensibly do with
two responses to the same request? Send only the first one to the
client? Compare if they are different and send an error if they are?

Or do you want to send only POSTS to multiple back-end systems to keep
them in sync somehow (not a reliable mechanism, as you will miss loads
of requests when a back-end is down)?

I tought as well the idea was pretty unusual, as it’s twice the work and
you
usually want to do as less as possible!
Anyway, depending on load, expected availability, if it’ a proof of
concept
or something like that, I’d work on a minimal, self rolled “duplexing
proxy”… a minimal version should be < 100 lines of ruby or similar
languages…but it really depends a lot on what’s needed.
If the idea was instead just that of benchmarking two different versions
of
some service, I’d rather record the requested urls and then play them
back
to different backends.
