+ * HTTP protocol interceptor is a routine that implements a specific aspect of

+ * 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
+ * <p>
+ * 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.
+ * <p>
+ * 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.
