openresty / ledge pass to fastcgi in cache miss?

I cant wrap my mind about where I combine nginx and openresty togther

I have this simple configure:

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;


    sendfile        on;
    keepalive_timeout  65;

        error_log logs/error.log debug;

        if_modified_since Off;
        lua_check_client_abort On;
        resolver 127.0.0.1;
        lua_package_path '/opt/ledge/lua-ffi-zlib/lib/?.lua;/opt/ledge/lua-resty-http/lib/?.lua;/opt/ledge/lua-resty-redis-connector/lib/?.lua;/opt/ledge/lua-resty-qless/lib/?.lua;/opt/ledge/lua-resty-cookie/lib/?.lua;/opt/ledge/ledge/lib/?.lua;;';

        init_by_lua_block {
            local ledge_m = require "ledge.ledge"
            ledge = ledge_m.new()
            ledge:config_set("esi_enabled", true)
            ledge:config_set("redis_host", { host = "<redis_ip>", port = 6379, password = "<password_here>", socket = nil})
            ledge:config_set("upstream_host", "<php_server_ip>")

        }

        init_worker_by_lua_block {
            ledge:run_workers()
        }

        server {
            location ~* \.(?:ico|css|js|gif|jpe?g|png)$ {
                proxy_pass http://<php_server_ip>$uri;
            }

            location / {
                content_by_lua_block {
                        ngx.req.clear_header('Cache-Control')
                        ngx.req.clear_header('Pragma')
                        ledge:bind("origin_fetched", function(res)
                          res.header["Cache-Control"] = "max-age=9999999"
                        end)


                    ledge:run()
                 }
            }
        }
}

so right now in cache miss I send the request to other "normal" nginx server that fastcgi_pass the request to php, is there a way to remove the middleware nginx server, and in cache miss directly connect to fastcgi ?

There's no need to have nginx and openresty running separately, anything nginx can do openresty can.

The most reliable way would be to have another server block in your openesty config that listens an a separate port and uses fastcgi_pass, then point Ledge at this.

e.g.

http {
  <default stuff here, init / init_worker etc>


    server {
        listen 80;
        <ledge stuff here>
    }
    server {
        listen 8080;
        <php fastcgi config here>
    }
}

Eventually it would be great to be able to use lua-resty-fastcgi to talk to PHP directly, then you could give that to Ledge and avoid any extra http hops.

However that library is not 100% yet, so it may or may not work for you.
