[NEW PORT] www/mod_dosevasive20: An Apache 2 module to try to protect HTTP DoS or DDoS attacks

	mod_dosevasive is an evasive maneuvers module for Apache
	to provide evasive action in the event of an HTTP DoS or
	DDoS attack or brute force attack.  It is also designed to
	be a detection and network management tool, and can be
	easily configured to talk to ipchains, firewalls, routers,
	and etcetera.  mod_dosevasive presently reports abuses via
	email and syslog facilities.

+mod_dosevasive is an evasive maneuvers module for Apache to provide evasive 
+action in the event of an HTTP DoS or DDoS attack or brute force attack.
+It is also designed to be a detection and network management tool, and can be
+easily configured to talk to ipchains, firewalls, routers, and etcetera.
+mod_dosevasive presently reports abuses via email and syslog facilities.
+
+Detection is performed by creating an internal dynamic hash table of IP
+Addresses and URIs, and denying any single IP address from any of the
+following:
+
+    * Requesting the same page more than a few times per second
+    * Making more than 50 concurrent requests on the same child per second
+    * Making any requests while temporarily blacklisted (on a blocking list) 
+
+This method has worked well in both single-server script attacks as well as
+distributed attacks, but just like other evasive tools, is only as useful to
+the point of bandwidth and processor consumption (e.g. the amount of bandwidth
+and processor required to receive/process/respond to invalid requests), which
+is why it's a good idea to integrate this with your firewalls and routers for
+maximum protection.
+
+This module instantiates for each listener individually, and therefore has a
+built-in cleanup mechanism and scaling capabilities. Because of this per-child
+design, legitimate requests are never compromised (even from proxies and NAT
+addresses) but only scripted attacks. Even a user repeatedly clicking on
+'reload' should not be affected unless they do it maliciously. mod_dosevasive
+is fully tweakable through the Apache configuration file, easy to incorporate
+into your web server, and easy to use.
