You need to have a "read-for-fill" operation ... In Squid 2.6: collapsed_forwarding on refresh_stale_window (apply the latter only to stanzas where you want "readahead" of about-to-expire cache entries) Brief design description at http://devel.squid-cache.org/collapsed_forwarding/. (I didn't write this code, everything I know about squid leaked through the Google-shaped pinhole in my tinfoil hat, etc. But if you go this way I'd like to be in the loop to understand the scalability issues around netfilter-assisted transparent proxying.)
