### Proxy buffering
Enable or disable proxy buffering [`proxy_buffering`](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffering).
By default proxy buffering is disabled in the nginx config.
To configure this setting globally for all Ingress rules, the `proxy-buffering` value may be set in the NGINX ConfigMap.
To use custom values in an Ingress rule define these annotation:
```yaml
nginx.ingress.kubernetes.io/proxy-buffering: "on"
```
