Deactivate Cache Headers when Authenticated.

[Natim]

When updating a collection, we should disable cache headers.

Regarding single record updates (PATCH/PUT), the response body will return the last version of the records.

So naively I would say that it concerns the GET record more than the collection.

Could you explain why you thought of collection specifically?

I suspect that when using KWAC to update the collection it can be difficult to sync your local records against a cached collection because each time you will call the sync you may get cached values.
Also if the _since changed inbetween, it will probably re-cache correctly but not necessarily with the right values for the public.

We may delay this until we see a problem to update cached collection but we should start thinking about problems when updating cached-collections.
