Recursive Request DoS

ha.ckers.org web application security lab

A self-inflicted denial of service against a server-side URL fetcher. Chaining url= parameters yields only a few iterations, but where the request key is predictable, a counter or timestamp rather than a hash, you can point request N at the URL carrying key N+1. The server then connects back to itself repeatedly, holding sockets and resources until they time out.
