Helo, I have many doubts about the operation and monitoring Cahe-digests. I do not know how to access the summaries created by the same, as I do?! I do not know how to ensure that all cache servers are utilising and swapping the summary cache_digests between them , is need a tag referencing she? The cache-digests is only an information exchange protocol between the caches that have to be used with a architecture of a squid (mesh, hierarquic, multicast)? Looking at my scenario, you can point my errors.
