To have one self containing class that can be plugged into any servlet container. Class will log everything about the request and response, including the payload data coming in and going out.
I need to dump out the payload for posts, gets and responses to troubleshoot some issues where data got mismatched between the request and response. Ideal solution would have all this data on one single line. Quick look around gave no off the shelf results, so I put together a quick Filter implementation to capture request and response data.
