I'm prepared to log both. My server will provide multiple logging
levels, and I will include perl scripts to turn any format into the
common log format for statistics packages. If it were one or the other, I
think most people would prefer knowing what data was sent to what was


This is a nice idea. The trick is getting support from the statistics
package writers and the server writers, because each would wait on the
other, I'd imagine.
