### External Authentication
To use an existing service that provides authentication the Ingress rule can be annotated with `nginx.ingress.kubernetes.io/auth-url` to indicate the URL where the HTTP request should be sent.
Additionally it is possible to set `nginx.ingress.kubernetes.io/auth-method` to specify the HTTP method to use (GET or POST).
```yaml
nginx.ingress.kubernetes.io/auth-url: "URL to the authentication service"
```
Additionally it is possible to set:
`nginx.ingress.kubernetes.io/auth-method`: `<Method>` to specify the HTTP method to use.
`nginx.ingress.kubernetes.io/auth-signin`: `<SignIn_URL>` to specify the location of the error page.
`nginx.ingress.kubernetes.io/auth-response-headers`: `<Response_Header_1, ..., Response_Header_n>` to specify headers to pass to backend once authorization request completes.
`nginx.ingress.kuberentes.io/auth-request-redirect`: `<Request_Redirect_URL>` to specify the X-Auth-Request-Redirect header value.
Please check the [external-auth](../examples/auth/external-auth/README.md) example.
