darkSheep404 opened a new issue, #11107:
URL: https://github.com/apache/apisix/issues/11107
### Description
we using upstream config in yml like that
```
upstreams:
- id: app
name: app
pass_host: node
nodes:
"app.test.com": 1
scheme: https
```
currently `app.test.com` point to 2 instance A (ip : 1.1.1) ,B (ip: 2.2.2)
if A down, `app.test.com` will auto point to B(ip: 2.2.2)
when using nginx
we can use below code to let nginx refresh ip of `app.test.com` every 10
seconds to ensure get the lastest ip
```
location /lst-dns-test/ {
resolver 6.6.6.6 valid=10s; # 6.6.6.6 is a dns server
set $proxy_url "app.test.com";
proxy_pass http://$proxy_url;
}
```
can we do this in apisix for below upstream ?
```
upstreams:
- id: app
name: app
pass_host: node
nodes:
"app.test.com": 1
scheme: https
```
### Environment
