i try squid 2.7 with the same config file (just add acl all ^_^)...
it can work normally and get 404 pages cache hit...

i saw the if (expires==0) expression in the source code.
and i am wondering why the expires should be zero here to get expires update.

void
StoreEntry::negativeCache()
{
    debugs(11, 3, "negativeCache: expires:" << expires);
    if (expires == 0)
#if HTTP_VIOLATIONS
{
        expires = squid_curtime + Config.negativeTtl;
        debugs(11, 3, "negativeCache: HTTP_VIOLATIONS: expires:" << expires << " squid_curtime:" << squid_curtime << "C
onfig.negativeTtl:" << Config.negativeTtl);
}
#else
        expires = squid_curtime;
#endif
    EBIT_SET(flags, ENTRY_NEGCACHED);
}
