Hello every guru, I got a TCP frontend and a HTTP backend, recently I have a issue some users send too much queries to one URL, maybe it's malware or autobot. So is it possible to limit one source IP to access api.example.com request rate at 30 per hour? The other hosts like www.example.com, mail.example.com not limited by that.
I refer to 1.5 doc and http://blog.haproxy.com/2012/02/27/use-a-load-balancer-as-a-first-row-of-defense-against-ddos/ , can't find a clear way to accomplish. Thanks. Bests, -Igor
