limit conn on specific ip

["ArioS" <christian@xxxxxxxxx>]

Dear,

is it possible for squid to limit conn ? since two days ago, i got DoS on my 
network to some sites (spamhaul / uribl etc). the trojan send hundred 
request / sec to the host. it was take down my proxy (running out of file 
descriptor). any possible way to avoid it ?

i tried to use acl to deny destinition host / ip... it was useless cause 
proxy still accept request.. now i just manual monitoring then block the ip 
using iptables.. anyone can help me ?
