This document outlines Hippo's 10 golden rules for Cocoon caching. The rules are: design for performance from the start; monitor performance after each change; cache as much as possible but nothing extra; cache for as long as possible but not too long; design pipelines for caching by cacheability; choose the right caching type; control cache keys for uniqueness; know what to cache where for efficiency; make HTTP headers work for caching; do not trust external proxies.
