Prize: One book of choice by O'Reilly		 The excess of simultaneous accesses to a site that may be happening in a given moment is one of the causes that can make a site run slower or even stop running.

Sometimes the excess of simultaneous accesses may be caused by a single user that is using automated robots to quickly retrieve all the site pages, or even by badly intentioned users that deliberately want to cause harm to the site by flooding it with an excessive number of simultaneous requests.

This class can help minimizing the harm that flood attempts may cause by keeping track of the IP addresses of the users accessing each page. Then it can determine when the users of a certain IP addresses are executing an excessive number of accesses so a block may be established for a given period.
