Prevent DoS attacks from occuring in various ways.

  • Limiting the number of queries/second from a particular ip address. Once the limit is reached, you can send a redirect to a cached error page to limit any further processing. You might also be able to get these IP address firewalled so that you don't have to process their requests at all. Limiting requests per IP address wont work very well though if the attacker forges the source IP address in the packets they are sending.
