Re: Nginx 3rd party sticky module with backup server

True, You are right.

The issue I am facing is

upstream myLoadBalancer {
> hash $upstream_addr;
> server remote1:port1;
> server remote1:port2;
> server remote2.:port1;
> }

say first server is selected from upstream. Since I have specified hash $upstream_addr, all subsequent requests go to this server. Even new requests. There is no new cookie or parameter to change it to next server for new set of stateful requests.

I think that is how generic hash works(not cookie based), dependiong on either request IP, request parameter, it sticks to a backend server.

So looks like not ideal in my scenario.

For Lua: https://github.com/openresty/lua-resty-upstream-healthcheck,

Is it available in nginx version 1.9, or it requires adding another module?
