Thanks @davsclaus and @oscerd
@samar-elsayed you can not put header directly to Caffeine. Set the data you want to cache to exchange body and then put into caffeine cache. In the second route get data from caffeine (it will be in exchange body) and then setHeader from the body.
```
- route:
id: route-cbf4
nodePrefixId: route-1f7
from:
id: from-7856
uri: kamelet:timer-source
parameters:
message: Hello
steps:
- setBody:
id: setBody-eaa0
expression:
simple:
id: simple-3dc1
expression: ${date:now}
- to:
id: to-604c
uri: caffeine-cache
parameters:
cacheName: demo1
action: PUT
key: key1
- route:
id: route-778e
nodePrefixId: route-289
from:
id: from-aedc
uri: kamelet:timer-source
parameters:
message: world
steps:
- to:
id: to-191e
uri: caffeine-cache
parameters:
cacheName: demo1
action: GET
key: key1
- log:
id: log-d474
message: ${body}
```

You can bind the cache to registry and re-use the same instance in multiple routes of the context https://camel.apache.org/components/4.0.x/caffeine-cache-component.html#_examples

its context scoped (in reality per component), also it creates a default in-memory cache if not specially created as the link from Andrea above.
