refresh_pattern defaults

[Thomas <thomas@xxxxxxxxxxxxx>]

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:

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!
