I saw this interesting request show up in my log file:

And then there's nothing noting what the response was, which should have been a 404 since I've no such host defined. I've got a valve defined that will intercept requests for a host not defined in server.xml and send back a 404 response instead of allowing the request to flow to the default host for the engine.



Under what conditions will Tomcat (5.0.19) not send (or log) any response?
