There have been some DoS attacks based on a url of the form:
http://localhost:19/whatever

From memory they affected Netscape Navigator and IE, and some web proxy 
software.

Whether this is the fault of the application for not having some limit to 
memory use is something that we can debate.  Chargen-TCP has been used as 
part of a DoS attack, and turning it off will alleviate some things.

Chargen-UDP is just a bad idea.
