### Sticky sessions
|
||||
|
||||
Sticky sessions are supported with both load balancers.
|
||||
When sticky sessions are enabled, a cookie called `_TRAEFIK_BACKEND` is set on the initial request.
|
||||
When sticky sessions are enabled, a cookie is set on the initial request.
|
||||
The default cookie name is an abbreviation of a sha1 (ex: `_1d52e`).
|
||||
On subsequent requests, the client will be directed to the backend stored in the cookie if it is still healthy.
|
||||
If not, a new backend will be assigned.
|
||||
|
||||
For example:
|
||||
To activate sticky session:
|
||||
|
||||
```toml
|
||||
[backends]
|
||||
[backends.backend1]
|
||||
[backends.backend1.loadbalancer.stickiness]
|
||||
```
|
||||
|
||||
To customize the cookie name:

|
||||
```toml

||||
[backends]
|
||||
[backends.backend1]
|
||||
[backends.backend1.loadbalancer.stickiness]
|
||||
cookieName = "my_cookie"

### Health Check
|
||||
|
||||
A health check can be configured in order to remove a backend from LB rotation as long as it keeps returning HTTP status codes other than `200 OK` to HTTP GET requests periodically carried out by Traefik.
|
||||
The check is defined by a pathappended to the backend URL and an interval (given in a format understood by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration)) specifying how often the health check should be executed (the default being 30 seconds).
|
||||
Each backend must respond to the health check within 5 seconds.

With some backends, the server URLs use the IP, so you may need to configure `InsecureSkipVerify` instead of the `RootCAS` to activate HTTPS without hostname verification.

## Conclusion
|
||||
|
||||
We don't need specific configuration to use gRPC in Træfik, we just need to be careful that all the exchanges (between client and Træfik, and between Træfik and backend) are valid HTTPS communications (without `InsecureSkipVerify` enabled) because gRPC use HTTP2.

So you could set `disablePassHostHeaders` to `true` in your toml file and then enable passing

|
||||
|
||||
## Excluding an ingress from Træfik
|
||||
## Partitioning the Ingress object space
|
||||
|
||||
You can control which ingress Træfik cares about by using the `kubernetes.io/ingress.class` annotation.
|
||||
By default, Træfik processes every Ingress objects it observes. At times, however, it may be desirable to ignore certain objects. The following sub-sections describe common use cases and how they can be handled with Træfik.
|
||||
|
||||
By default if the annotation is not set at all Træfik will include the ingress.
|
||||
If the annotation is set to anything other than traefik or a blank string Træfik will ignore it.
|
||||
### Between Træfik and other Ingress controller implementations
|
||||
|
||||
Sometimes Træfik runs along other Ingress controller implementations. One such example is when both Træfik and a cloud provider Ingress controller are active.
|
||||
|
||||
The `kubernetes.io/ingress.class` annotation can be attached to any Ingress object in order to control whether Træfik should handle it.
|
||||
|
||||
If the annotation is missing, contains an empty value, or the value `traefik`, then the Træfik controller will take responsibility and process the associated Ingress object. If the annotation contains any other value (usually the name of a different Ingress controller), Træfik will ignore the object.
|
||||
|
||||
### Between multiple Træfik Deployments
|
||||
|
||||
Sometimes multiple Træfik Deployments are supposed to run concurrently. For instance, it is conceivable to have one Deployment deal with internal and another one with external traffic.
|
||||
|
||||
For such cases, it is advisable to classify Ingress objects through a label and configure the `labelSelector` option per each Træfik Deployment accordingly. To stick with the internal/external example above, all Ingress objects meant for internal traffic could receive a `traffic-type: internal` label while objects designated for external traffic receive a `traffic-type: external` label. The label selectors on the Træfik Deployments would then be `traffic-type=internal` and `traffic-type=external`, respectively.
