Just two quick notes. If you want the same request pattern, I assume that
is because you want the workload to be the same for all of your tests.
Well, the latter is not, strictly speaking, possible if you are going to
use life servers on the Internet. Second, if you are OK with synthetic
workloads, you may give Web Polygraph a shot. You will have to build your
own workload, but it may be doable. Also, note that there is at least one
existing study comparing ICP with Cache Digests (see FAQ).
