Hi,

is it a bug or a feature that nginx didn’t warn if keepalive is enable  
in upstream {} config, but without ngx\_http\_upstream\_keepalive module  
loaded ?

Regards,

If upstream keepalive module isn’t compiled in the following

upstream {
    server 127.0.0.1:8080;
    keepalive 5;
}

```

produces the following error during configuration parsing:

nginx: [emerg] unknown directive “keepalive” in …
