Dear List,

we use the upstream module to proxy requests to our backend, as much  
other people 😉

I want to check if I have understand the

rrp-\>peers-\>single in src/http/ngx\_http\_upstream\_round\_robin.c

flag in the correct manner.

At the moment we have only one upstream and we have te following in our  
config.

upstream backend1 {  
server 172.16.2.1 weight=10 max\_fails=3 fail\_timeout=30s;  
}

If the server 172.16.2.1 is not reachable then the request is gone,  
right?

A possible solution is to add the same server several times, right?  
Is there another, better solution to resend the request to the backend?

BR

Aleks
