Anyone ever suggested? No idea. But I'd be glad to riff on the subject in case it shakes some discussion loose.
I haven't seen a filter like that, but I'm sure you could work it out. If I were implementing it I would use a Valve... Valves are easy to write- just extend org.apache.catalina.valves.ValveBase and wire it into your xml configurations. You could probably be more sophisticated in your throttling, letting certain IPs or requests through while tarpitting others. A number of considerations; these off the top of my head-- You'd have to be okay with holding the request thread open and making it sleep. I guess you could serve a 503 if it were overloaded. Consider your memory usage. I've read horror stories about GC pauses wreaking havoc. If you have a farm of tomcats that would be participating you'd need to work out a way for them to communicate with one another for global counter stats.
