Hi team

I have strange issue with reverse proxy configuration. I'm using reverse proxy configuration due to SSL from sha1 to sha256 transformation with proxy pass configuration

"proxy_pass https://abc.mydomain.com/;"

When we update the abc.mydomain.com dns record, nginx still resolve old ip address until it's restarted.

But Operating System resolving new ip address.

What may cause this issue ? it looks ssl session caching issue but i'm not sure.

Here is session configs

ssl_session_cache builtin:1000 shared:SSL:10m;

Thank you.

Hi team

Issue sort out. It's by desing. when nginx starting it's load all records own memory. if you can solve this issue you can use dynamic upstream's or resolver configuration http,server or location context.

Thank you.
