RE: [squid-users] 302 response becomes not cacheable with "if-modified-since" header?

Hi Odhiambo,

Thanks for the suggestions. I have checked out STABLE11
source code and I believe the behavior is the same. So,
do you think this is a bug? Is there any workaround you
are aware of? Any help will be greatly appreciated.

Thanks,

--Chris

        /*
         * Handle If-Modified-Since requests from the client
         */
        if (mem->reply->sline.status != HTTP_OK) {
            debug(33, 4) ("clientCacheHit: Reply code %d != 200\n",
                mem->reply->sline.status);
            memFree(buf, MEM_CLIENT_SOCK_BUF);
            http->log_type = LOG_TCP_MISS;
            clientProcessMiss(http);
        }
