OT? Device to limit simultaneous connections per host?

Hello everyone, I'm curious if anyone knows of a device that can throttle or limit a remote host's simultaneous connections or requests per second for web traffic on a per-IP basis. So I don't want to say web server X can only have 100 simultaneous connections and 10 requests per second. I want to say that for any given IP connecting to web server X, any one IP can have no more than 5 open connections and should be throttled if it starts making more than ten requests per second. If it could even be url-aware in that it could only apply the rules to specific types of web requests, that would be even better. The motivation here is to find a piece of equipment that can protect compute-intensive, database-driven websites from overly aggressive proxies, firewalls, search engines, etc. which like to hammer a given site with 50+ simultaneous requests against pages that could potentially need a few seconds of processing time per request. I've looked at a Packeteer PacketShaper running in reverse of what it normally would, trying to throttle and shape requests against the server rather than optimizing traffic for a low speed link like it was designed, but that didn't really work out as it could not have the policies applied on a per remote IP basis. Thanks, David
