Hello

My config haproxy.cfg

frontend sait  
bind \*:7030

```
acl hdr_sait hdr_beg(host) -i sait.ru
acl status_404 status 404
http-response set-header Location https://sait.ru/ErrorPages/404_ru.html if status_404
http-response set-status 302 if status_404

acl status_5xx status 500 502 503 504
http-response set-header Location https://sait.ru/ErrorPages/503.html if status_5xx
http-response set-status 302 if status_5xx

```

acl path\_4 path\_beg /ErrorPages/  
use\_backend bknd\_nginx if hdr\_sait path\_4  
use\_backend bknd\_tomcat if hdr\_sait

how can I make sure that the correct http codes 404, 503,500 are given to a higher-standing server. And not 302 ?

I’ve been here so that only nginx does this, but the config test shows warning

frontend sait  
bind \*:7030

```
acl hdr_sait hdr_beg(host) -i sait.ru
acl status_404 status 404
acl status_5xx status 500 502 503 504

```

use\_backend bknd\_nginx if hdr\_sait status\_404  
use\_backend bknd\_nginx if hdr\_sait status\_5xx  
use\_backend bknd\_tomcat if hdr\_sait

acl ‘status\_404’ will never match because it only involves keywords that are incompatible with ‘frontend use-backend rule’

`use_backend` is a client-\>server feature and `status` is a fetch which works on the way server-\>client.  
In other terms, you can’t use a “response phase” feature at request time

Are there any ways to change 302 to 404?
