1093	Support http_429 in *_cache_use_stale	tvdavid@…		"Use case: we use nginx with fastcgi_cache to cache responses from a backend application. Clients can request nginx-cached endpoints without limits, but the backend performs rate limiting to protect itself by returning a HTTP 429 if the limit is exceeded.

It would be very useful to allow serving a stale cache entry when the upstream returns a 429, since the client would probably prefer a stale reply over no reply at all."	enhancement	closed	minor		nginx-module	1.11.x	fixed				1.11
