mod_evasive 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 tool, and can be easily
configured to talk to ipchains, firewalls, routers,
and etcetera.

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)
