### Client Body Buffer Size
Sets buffer size for reading client request body per location. In case the request body is larger than the buffer,
the whole body or only its part is written to a temporary file. By default, buffer size is equal to two memory pages.
This is 8K on x86, other 32-bit platforms, and x86-64. It is usually 16K on other 64-bit platforms. This annotation is
applied to each location provided in the ingress rule.
*Note:* The annotation value must be given in a valid format otherwise the
For example to set the client-body-buffer-size the following can be done:
* `ingress.kubernetes.io/client-body-buffer-size: "1000"` # 1000 bytes
* `ingress.kubernetes.io/client-body-buffer-size: 1k` # 1 kilobyte
* `ingress.kubernetes.io/client-body-buffer-size: 1K` # 1 kilobyte
* `ingress.kubernetes.io/client-body-buffer-size: 1m` # 1 megabyte
* `ingress.kubernetes.io/client-body-buffer-size: 1M` # 1 megabyte
For more information please see http://nginx.org/en/docs/http/ngx_http_core_module.html#client_body_buffer_size
### External Authentication
To use an existing service that provides authentication the Ingress rule can be annotated with `ingress.kubernetes.io/auth-url` to indicate the URL where the HTTP request should be sent.
