Slowloris is a little complicated to mitigate, because it simulate a
real conection. I've used some rules on iptables based on packet
count/seconds if the access activate the rule it will be about 5 seconds
blocked....

But first you need to have some ideia about the real traffic and users
access from proxy.

Blocking this attack using -j reject isnt a good solve, because you use
some bandwidth generating the bad response, -j drop works fine.
