I use them for authentication.. Filter is mainly a pre-processor or a post-processor however you want to use it..
It is pretty good for taking code out code that is in EACH one or most of your servlets or jsps. By using filter, you can do *those* tasks before the request gets to them. I think filters are very good.. After all, if your filter is slow, you can speed it up by making changes at one place, the filter. And I don't really see much overheard. Generally you don't put a "do nothing" filter on every request, filter will do something that's needed for the app. Other than that, its just another class that gets loaded. I am not an expert at exactly these application servers deal with them, but I do know that I wanted filters way before they came out, so I am a big fan of em.. My 2 cents..
