    # The hash table size defines the number of top-level nodes for each

    # child's hash table.  Increasing this number will provide faster

    # performance by decreasing the number of iterations required to get to the

    # record, but consume more memory for table space.  You should increase

    # this if you have a busy web server.  The value you specify will

    # automatically be tiered up to the next prime number in the primes list

    # (see mod_evasive.c for a list of primes used).

    # This is the threshhold for the number of requests for the same page (or

    # URI) per page interval.  Once the threshhold for that interval has been

    # exceeded, the IP address of the client will be added to the blocking

    # list.

    DOSPageCount        2

    # This is the threshhold for the total number of requests for any object by

    # the same client on the same listener per site interval.  Once the

    # threshhold for that interval has been exceeded, the IP address of the

    # client will be added to the blocking list.

      # The blocking period is the amount of time (in seconds) that a client will

      # be blocked for if they are added to the blocking list.  During this time,

      # all subsequent requests from the client will result in a 403 (Forbidden)

      # and the timer being reset (e.g. another 10 seconds).  Since the timer is

      # reset for every subsequent request, it is not necessary to have a long

      # blocking period; in the event of a DoS attack, this timer will keep

      # getting reset.
