When the [`custom-http-errors`][cm-custom-http-errors] option is enabled, the Ingress controller configures NGINX so
that it passes several HTTP headers down to its `default-backend` in case of error:
| Header | Value |
| ---------------- | ------------------------------------------------ |
| `X-Code` | HTTP status code retuned by the request |
| `X-Format` | Value of the `Accept` header sent by the client |
| `X-Original-URI` | URI that caused the error |
| `X-Namespace` | Namespace where the backend Service is located |
| `X-Ingress-Name` | Name of the Ingress where the backend is defined |
| `X-Service-Name` | Name of the Service backing the backend |
| `X-Service-Port` | Port number of the Service backing the backend |
| Header | Value |
| ---------------- | ------------------------------------------------------------------- |
| `X-Code` | HTTP status code retuned by the request |
| `X-Format` | Value of the `Accept` header sent by the client |
| `X-Original-URI` | URI that caused the error |
| `X-Namespace` | Namespace where the backend Service is located |
| `X-Ingress-Name` | Name of the Ingress where the backend is defined |
| `X-Service-Name` | Name of the Service backing the backend |
| `X-Service-Port` | Port number of the Service backing the backend |
| `X-Request-ID` | Unique ID that identifies the request - same as for backend service |
A custom error backend can use this information to return the best possible representation of an error page. For
example, if the value of the `Accept` header send by the client was `application/json`, a carefully crafted backend
