annotate src/http/modules/ngx_http_scgi_module.c @ 5832:d09b689911ac
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.
