Hi Kevin, I want to try both. Cache Digest and no-digest, because I want to run two benchmarks. Cache-Digests it's very very useful if you have mid/high latency between squids. Since my latency it's <1 ms, ICP isn't a big problem for me. I can afford an ICP request per every HTTP request. But of course i won't discard using Cache Digest to see what is better in my case. Thanks a lot!
