Is it possible to mirror the HTTP Traffic to a separate server to perform independent process (no response needed) while at the same time serving the original requests?
Preferably I would like to do it using built in directives from nginx. Something like this.
It may be possible in Nginx with post_action (found using Google search). You could also consider using GOR to do this.
Some kind of log file processing could be simpler, either near realtime or batch.
Not possible. HTTP requires responses both ways, you can't mirror it. If you want to you could duplicate the payloads of the HTTP messages by writing them to a queue and then copying the queue and sending it to multiple places. This is what ActiveMQ/RabbitMQ is all about.
But not just with HTTP itself.
