Usually protocol interceptors are expected to act upon one specific header or a group of related headers of the incoming message or populate the outgoing message with one specific header or a group of related headers. Protocol

Interceptors can also manipulate content entities enclosed with messages. Usually this is accomplished by using the 'Decorator' pattern where a wrapper entity class is used to decorate the original entity.

Protocol interceptors must be implemented as thread-safe. Similarly to servlets, protocol interceptors should not use instance variables unless access to those variables is synchronized.
