Traffic mirroring with nginx

Question

Simply put using Nginx I am trying to mirror all the traffic hitting one of our apps, app A to a newly deployed test app. I know that there is the mirror module but I was wondering if there is any other way to implement this? Even if it's not thru Nginx.

Cheers,

there is a directive called post_action, but I am not sure if it will stop any response from the test app. — Omera, Mar 29 '23 at 05:50

You could use your physical hardware or maybe even the cloud service.

You could also do it with your linux server ( see example here ).

I'm guessing running it on the cloud will cost money, while running it on the VM will demand some CPU - but I never tried to do that.

I ended up upgrading nginx as the post_action directive didn't work for me.
