Okay, I've got my filter written. A reminder of the requirements:

- - Capture request as seen by the application
- - Capture response emitted by the /application/

Note that the last requirement does not include standard headers such as
"Date" and the default status code. Only messages actually generated by
the application are captured.

For those interested in seeing some techniques, these items are covered
by the code:

- - how to wrap a servlet input stream and reader
- - how to make a copy of streaming data
- - how to figure out which request parameters are GET versus POST
- - how to wrap a servlet output stream and writer

Again, comments and questions are welcome.

Enjoy,
- -chris
