[squid-users] refresh_pattern defaults

Hi guys,

I've been searching for a while and could not find the answer to the
'refresh_pattern' default values if they're NOT defined in the
configuration. On the config website it mentions "none" which I don't
understand, because in order to calculate this:

>> How does Squid decide when to refresh a cached object

if (EXPIRES) {
         if (EXPIRES <= NOW)
             return STALE
         else
             return FRESH
     }
     if (CLIENT_MAX_AGE)
         if (OBJ_AGE > CLIENT_MAX_AGE)
             return STALE
     if (OBJ_AGE > CONF_MAX)
         return STALE
     if (OBJ_DATE > OBJ_LASTMOD) {
         if (LM_FACTOR < CONF_PERCENT)
             return FRESH
         else
             return STALE
     }
     if (OBJ_AGE <= CONF_MIN)
         return FRESH
     return STALE

We need the refresh_pattern config values? I'm at a loss, have asked a
good few linux friends etc using squid for a while with no good reply.

Technical details:

OS: Debian 6
Package installed: 3.1.6-1.2+squeeze2

Any ideas?

Cheers guys!
