- Another possible value for `extractorfunc` is `client.ip` which will categorize requests based on client source ip.
- Lastly `extractorfunc` can take the value of `request.header.ANY_HEADER` which will categorize requests based on `ANY_HEADER` that you provide.
Sticky sessions are supported with both load balancers. When sticky sessions are enabled, a cookie called `_TRAEFIK_BACKEND` is set on the initial
request. 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:
```toml
[backends]
[backends.backend1]
[backends.backend1.loadbalancer]
sticky = true
```
## Servers
Servers are simply defined using a `URL`. You can also apply a custom `weight` to each server (this will be used by load-balancing).
