Hi,

I've also used filters, but in this case to filter requests by IP, as I
don't want certain IP's to be able to access certain URLs. On the other
hand, I implemented security, logging and other features inside my own
servlet Controller, following a Model 2 approach. I thought about
"externalizing" this services as filters, but that would mean that the
web.xml file will grow too much and that I would have to put too much
things in the request object each time. It's not that I've discarded the
idea, but I don't see any compelling reason to implement everything as
filters. We don't use servlets, but ONE controller servlet and action
classes and we use JSP as view-only, creatures (actually, we seldom use
them as we use XML/XSLT), so as anyway all the requests go through my
controller servlet... We implemented IP filtering as a filter because we
also wanted to use it in other applications, as well as with static
content.
Just my 2c,
D.
