Hi Mike,
It looks like are reading documentation for 1.x versions of Web
Polygraph. The experiment configuration has changed a lot since then. We
now use PGL configuration files to describe the workload. See examples
in the "workloads" directory of your Polygraph distribution.
To answer your specific questions, you can use the working_set_length()
PGL function to "freeze" working set size after a given period of time.
For details, see PolMix-2 discussion at
http://polygraph.ircache.net/Workloads/
You can simulate cachable miss-only stream with PGL. However you cannot,
at the moment, repeat the experiment with exactly the same sequence of
URLs. The models became too complex and nobody asked for that feature so
it got deleted from Polygraph. What exactly are you trying to achieve
with that test? Perhaps we can think of a workaround...
Alex.
