Yes, and a bit more..

int
isTcpHit(log_type code)
{
    /* this should be a bitmap for better optimization */
    if (code == LOG_TCP_HIT)
        return 1;
    if (code == LOG_TCP_IMS_HIT)
        return 1;
    if (code == LOG_TCP_REFRESH_FAIL_HIT)
        return 1;
    if (code == LOG_TCP_REFRESH_HIT)
        return 1;
    if (code == LOG_TCP_NEGATIVE_HIT)
        return 1;
    if (code == LOG_TCP_MEM_HIT)
        return 1;
    if (code == LOG_TCP_OFFLINE_HIT)
        return 1;
    return 0;
}

It's a bit of an approximation as there is no exact hit/miss semantics
in HTTP caches. The cache validations lives somewhere between hit/miss.
