I'm configuring a failover server tasked to accept any incoming request, and reply with blank 200 response. The idea is to minimize the reply time and to ensure we dont send any 40x or 50x.
I tried using
return 200; for the desired locations within Nginx, but my monitoring systems (Pingdom) didn't like the response, and consider the server not responding.
Is there a better way to do this, of course with minimal overhead on the server?
