I understand you're working on a reverse-proxy setup. In such a case I
would recommend you not to do any inter-cache synchronization at all,
since it would add latency to misses, while in your scenario going to
the origin server is not very expensive.
AT MOST you may want to use cache digests, but I wouldn't expect you'd
gain significant performance out of it.
