| HTTP protocol interceptor is a routine that implements a specific aspect of |
| the HTTP protocol. 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. |
| <p> |
| 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. |
| <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. |
