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

Thanks, Henrik pal!

I think I should take some time to read FAQ and squid.conf
clearly. :-)

I still have a question, after reading FAQ and squid.conf,
and http_status in enum.h, I still puzzled at such statement.

     if (http->redirect.status) {
         /* force this to be a miss */
         http->entry = NULL;
         return LOG_TCP_MISS;

I do not understand the relationship between LOG_TCP_MISS and
the case that the variable "http->redirect.status" is not null.

IMHO, I think when http->redirect.status is not null, it indicates
a http redirect. Am I correct? But a http redirect is always cache
miss?

Best regards,
George, Ma
