Hello,

Given my nginx (as a http reverse proxy) has two backend servers, one  
is 192.168.1.1, another is 192.168.1.2  
When a request income, I want to pass it to the both application  
servers.  
Can I setup nginx doing it? and how?

Thanks.

You should look at HttpLuaModule:

> **[Lua | NGINX](https://www.nginx.com/resources/wiki/modules/lua/)**
>
> The Lua module embeds Lua into NGINX and by leveraging NGINX's subrequests, allows the integration of Lua threads into the NGINX event model.

Example:  
– construct the requests table  
local reqs = {}  
table.insert(reqs, { “/mysql” })  
table.insert(reqs, { “/postgres” })  
table.insert(reqs, { “/redis” })  
table.insert(reqs, { “/memcached” })

```
-- issue all the requests at once and wait until they all return
local resps = { ngx.location.capture_multi(reqs) }

-- loop over the responses table
for i, resp in ipairs(resps) do
    -- process the response table "resp"
end

```
