+Slowloris both helps identify the timeout windows of a HTTP server or Proxy
+server, can bypass httpready protection and ultimately performs a fairly low
+bandwidth denial of service.  It has the added benefit of allowing the server
+to come back at any time (once the program is killed), and not spamming the
+logs excessively.  It also keeps the load nice and low on the target server, so
+other vital processes don't die unexpectedly, or cause alarm to anyone who is
+logged into the server for other reasons.
+
+The main audience using slowloris is of course a system administrators wanting
+to measure their webserver's performance and vulnerability.
