Crash my webserver, please (no DDoS)

Hi there, I'm developing a small HTTP webserver named serverino. Serverino is supposed to work as proxy under a full webserver, like nginx. I wonder if you can help me testing it not ddos-ing/spamming requests but trying to crash it with bad/strange/malformed requests. There is an instance running on a small server online here: http://test.andreafontana.it (https too), shielded under nginx. The same instance is running on-the-wild on port 57123.
