Timeout for subrequest

hendersson

Hi,
Is it possible to set the timeout separately for each subrequest in capture_multi?
Something like:
local res_main, res_guard = ngx.location.capture_multi {
          {
            "/main" .. ngx.var.uri, { copy_all_vars = true, always_forward_body = true, timeout = 30000 } -- (in milliseconds)
          },
          {
              "/static/lore_ipsum.txt", { timeout = 60000 }
          }
      }

Or i should use "proxy_read_timeout" for every location/upstream ?

No, the subrequest mechanism does not provide timeout protection
itself. Rather, your location targeted by the subrequests control the
timeout protection. See

Alas, these proxy_xxx_timeout directives do not support nginx
variables. Otherwise you can pass such settings via different variable
bindings (via the `vars` option). CloudFlare's private fork of nginx
does allow this. Maybe we could backport it to OpenResty's bundled
version of the nginx core :)
