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.
Lee
