Thanks Jordi, I had overlooked the 'Clear cookies' checkbox. Not a JMeter question per se, but a JMeter test technique question for sure - If I keep iterating, and leave the servlet and container some pauses occasionally, why won't garbage collection keep the container alive provided I've provided enough memory using -Xmx -Xms and don't invoke any more simultanous sessions than that memory allotment allows?
Also, I still want to invoke JMeter in batch mode ... so I'd appreciate anyone's advice on how to resolve the java.util.zip.ZipException problem. Thanks.
