Handle messages related with basic request information.
This object can handle the following incoming messages:
- "FORWARD_REQUEST" input message ( sent when a request is passed from the web server )
- "PING REQUEST" input message (sent by the web server to determine if tomcat is not frozen,
a PONG REPLY will be sent back)
- "RECEIVE_BODY_CHUNK" input ( sent by container to pass more body, in response to GET_BODY_CHUNK )
It can handle the following outgoing messages:
- SEND_HEADERS. Pass the status code and headers.
- SEND_BODY_CHUNK. Send a chunk of body
- GET_BODY_CHUNK. Request a chunk of body data
- END_RESPONSE. Notify the end of a request processing.
