In Squid 2.6:
    collapsed_forwarding on
    refresh_stale_window <seconds>
(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.)

Cheers,
