Besides the `hosts` and `gatewayRefs` fields, you can customize the generated HTTPRoute with various options
exposed under the `spec.service` field of the Canary.
### Timeouts
You can configure request timeouts on the generated HTTPRoute using the `spec.service.timeout` and
`spec.service.backendTimeout` fields of the Canary. Both values are
[Gateway API Duration](https://gateway-api.sigs.k8s.io/geps/gep-2257/) strings (e.g. `5s`, `500ms`).
- `timeout` maps to `HTTPRouteTimeouts.Request` and bounds the total request duration from when the gateway
receives the request to when the response is sent back to the client.
- `backendTimeout` maps to `HTTPRouteTimeouts.BackendRequest` and bounds the duration of an individual
request from the gateway to a backend. When set together with `timeout`, `backendTimeout` must be
less than or equal to `timeout`.
> **Note:** Timeouts require a Gateway API implementation that supports
> [`HTTPRouteTimeouts`](https://gateway-api.sigs.k8s.io/api-types/httproute/#timeouts).
> `backendTimeout` additionally requires support for the `BackendRequest` timeout field.
Example configuration:
```yaml
apiVersion: flagger.app/v1beta1
kind: Canary
metadata:
name: podinfo
namespace: test
spec:
service:
# Total request timeout (gateway to client)
timeout: 5s
# Per-attempt backend request timeout (gateway to backend)
backendTimeout: 2s
```
### Header Manipulation
You can configure request and response header manipulation using the `spec.service.headers` field of the Canary.
