Description

The Exchange headers are sent to target systems in some components such as JMS (as JMS message headers), HTTP (as HTTP headers).

In order to send only some of the existing Exchange headers, without removing the undesired ones so they are available later on on the route, a filter strategy kicks in.

The current implementation of the DefaultHeaderFilterStrategy class match action removes the headers you configure, so is exactly the reverse of this use case.

With this modification, you'd keep some headers and you'd avoid sending anything not matched, preventing any information to be leaked.

The default value for this new setting keeps the current behaviour, so it should be safe to be introduced.
