Hey, I’m deploying my mail server and use nginx as the mail proxy. I  
tend to use multiple http\_auth servers to balance the load. Can I write  
multiple “http\_auth” directives? Or can I use a upstream block to  
indicate those servers?

Many thanks.

No.

Usual aproach is to configure http in the same nginx and  
proxy\_pass/fastcgi\_pass/whatever with appropriate balancing and  
redundancy, e.g.

mail {  
auth\_http 127.0.0.1:8080/mailauth;  
}

http {  
upstream auth-backends {  
server …  
server …  
}

```
server {
    listen 127.0.0.1:8080;

    location = /mailauth {
        proxy_pass http://auth-backends;
    }
}

```
