Comment 2 Marc Schoenefeld 2009-06-03 16:05:12 UTC

If Tomcat receives a request with invalid headers via the Java AJP connector, it does not return an error and instead closes the AJP connection. In case this connector is member of a mod_jk load balancing worker, this member will be put into an error state and will be blocked from use for approximately one minute. Thus the behaviour can be used for a denial of service attack using a carefully crafted request.
