I found it easy (compared to the alternatives) and efficient, and no I don't know of any other ways of blocking the attack, short of using Varnish or similar. However, accf_http doesn't help at all, since HTTP POST requests bypass the filter. HTTP POST can be enabled by passing the -httpready switch to Slowloris. Please report back with your findings, I've been wondering how it would perform under load. Best of luck with it, Thomas Rasmussen
