I expect it will apply to sessions as well, but I haven't confirmed that. You may want to experiment, and then let us all know.

This behaviour should also be assumed when using wsesslog workload
generator? I mean,
if a session accomplish 8 requests and I'd like a session timeout of 8
seconds, should I use
'--timeout 0.8' (connection establishment + 8 requests + close) ?
