Subject RE: Logging filter (was RE: [next] What's next ?)

Thanks for the response wrapper idea and skeleton -- that seems to solve
most of the problems we discussed.

This is a problem.  I also think until servlet spec 2.4, filters don't
see requests from request dispatchers, right?

How can we get around this, if at all possible, with a portable filter?

>* Filters only see the requests for their particular webapp.

It also just occurred to me that a legitimate, common use-case of these
access logs is for broken link analysis.  Having the filter just for the
webapp would miss out on all requests outside the webapp like you say.
Even if there's only one webapp installed on the server, you'd still
miss out on broken links.

True, and there's the role separation idea between developer delivering
the webapp and deployer/sysadmin controlling the server.  The current
Valve implementation nicely separates those human roles, which my Filter
idea would kind of break...
