Description

It could be useful to be able to limit proxy_next_upstream by number of tries or by time.

Something like:

proxy_next_upstream error timeout http_502 http_504;
proxy_next_tries 5;
proxy_next_timeout 10s;

In d09b689911ac2a3236f0fea322088e586814f9f8/nginx:

Upstream: limited next_upstream time and tries (ticket #544).

The new directives {proxy,fastcgi,scgi,uwsgi,memcached}_next_upstream_tries
and {proxy,fastcgi,scgi,uwsgi,memcached}_next_upstream_timeout limit
the number of upstreams tried and the maximum time spent for these tries
when searching for a valid upstream.
