Maximum number of backends to try

[Avleen Vig]

Hi guys,

I thought I saw a setting, which told nginx how many backend servers
to try before giving up.

I have an upstream with 10+ servers, and I only want to try queries on
two or three servers before giving up.

Anyone remember how to do this? Or am I going mad?

This is on nginx 0.7.63.

Thanks :)
