Turn on "option httplog", these information are available (read the relevant part of the documentation to find where). > 2) Is there a way to anti-DDOS based on a cookie?

But HAProxy could perform the same on a cookie. > 5) Is there a relatively simple way to get "true HA" with a redundant load > balancer?
