Web Application Firewall / Reverse Proxy: QoS or Rate Limit HTTP/S requests

I am discovering that at times, our web servers behind the UTM's reverse proxy get overloaded with too many HTTP/S requests. I'm curious to know if there is a way to rate limit HTTP/S requests from a certain IP address - say, not more than 20-40 requests/sec. I know there is TCP/UDP/ICMP flood protection settings, but I'm thinking of a smarter rate limiter (during L7 HTTP packet inspection & URI forwarding). I did not find any options in the Webserver Protection section - in the Firewall Profiles nor the Site Path Routing tabs. Should I be looking in another spot, or is this not possible?

Cheers!

The only thing I can think of, SAM, is a Download Throttling rule by source. That won't work though if the servers also receive uploads and not just requests.

This sounds like a great idea. You should make a suggestion at Ideas.
