You seem to be quite on track: Just remember the following simple guidelines:
1) If in a caching pipeline, cocoon tries to cache each pipeline match (thus the map:part in an aggregator or a src="cocoon:/..." it will try to cache the seperate pipeline matches, as well as the total) 2) Cocoon can ONLY cache a pipeline, if every single component is cacheable. So, in your case, 1) will be cached, and 2) wont be cached. So the first match is on 2), cocoon cant find a cached response because not every part of the pipeline can be cached. It will re-generate the entire pipeline, beginning with the cocoon:/siteData. But for this cocoon:/siteData, it will find a cached pipeline result.
