### Proxy buffer Number
Sets the number of the buffer in [`proxy_buffers`](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffers) used for reading the first part of the response received from the proxied server.
By default proxy buffer number is set as 4
To configure this setting globally, set `proxy-buffer-number` in [NGINX ConfigMap](./configmap.md#proxy-buffer-number). To use custom values in an Ingress rule, define this annotation:
```yaml
nginx.ingress.kubernetes.io/proxy-buffer-number: "4"
```
### Proxy buffer size
Sets the size of the buffer [`proxy_buffer_size`](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffer_size) used for reading the first part of the response received from the proxied server.
