Puzzled at clientProcessRequest2 in squid-2.5.PRE6. :-(

Hi, pals!

I am using squid-2.5.PRE6, In function clientProcessRequest2,
I am puzzled at the following statements,
    if (Config.onoff.offline) {
        debug(33, 3) ("clientProcessRequest2: offline HIT\n");
        http->entry = e;
        return LOG_TCP_HIT;
    }
    if (http->redirect.status) {
        /* force this to be a miss */
        http->entry = NULL;
        return LOG_TCP_MISS;
    }
    if (!storeEntryValidToSend(e)) {
        debug(33, 3) ("clientProcessRequest2: !storeEntryValidToSend MISS\n");
        http->entry = NULL;
        return LOG_TCP_MISS;
    }

What is the meaning and function of Config.onoff.offline, http->redirect.status and storeEntryValidToSend?

I think LOG_TCP_HIT indicates a cache HIT and LOG_TCP_MISS indicates a cache MISS.
Am I correct?

Best regards,
George, Ma
