No movement I am aware of. > Can anyone suggest a way to > disable this "feature" short of hacking tomcat? You don't want to disable sending 100 Continue responses. Ideally, you want to delay when it is sent until after any authentication (so the 401 goes back to the client before they send the body). I'm not sure how feasible that would be. Is your servlet generating the 401? It it was a standard authenticator generating the 401 it might be doable. If it is a user servlet then that is going to be trickier. It doesn't help that the Servlet API has no mechanism for sending a 101.
