You're totally right, you can't do a multi-level cache in this way (actually with squid the only multi-level you can do right now is with cache_mem - kinda sorta) Maybe I misunderstood your usage scenario: I thought you were in a reverse proxy scenario, and in that case the cost for populating the cache from scratch is not high. Also, system reboots are not that frequent anymore nowadays (I've had reverse-proxy systems where the OS would run for 1.5 years and squid processes would run for 6+ months without restarting).
