During my peak times, I use the following config to help my toplevel
caches back onto their feet (as suggested by one of the Squid gurus):

        acl noonish time MTWHF 11:50-12:10
        acl noonish time MTWHF 12:50-13:10
        acl noonish time MTWHF 13:50-14:10
        acl noonish time MTWHF 14:50-15:10
        no_cache deny noonish
