obj.status and obj.cacheable in varnish 2.1

[David Murphy]

Snippet from my vcl working under 2.1, which includes some debug header responses ( http://varnish-cache.org/wiki/VCLExampleHitMissHeader ) to see what's going in:

  # Varnish determined the object was not cacheable
    if (!beresp.cacheable) {
        set beresp.http.X-Cacheable = "NO:Not Cacheable";

    # You don't wish to cache content for logged in users
    } elsif(req.http.Cookie ~"(UserID|_session)") {
        set beresp.http.X-Cacheable = "NO:Got Session";
        return(pass);

    # You are respecting the Cache-Control=private header from the backend
    } elsif ( beresp.http.Cache-Control ~ "private") {
        set beresp.http.X-Cacheable = "NO:Cache-Control=private";
        return(pass);

    # You are extending the lifetime of the object artificially
    } elsif ( beresp.ttl < 1s ) {
        set beresp.ttl   = 5s;
        set beresp.grace = 5s;
        set beresp.http.X-Cacheable = "YES:FORCED";

   # Varnish determined the object was cacheable
    } else {
	set beresp.http.X-Cacheable = "YES";
    }

Best, David

Thanks David,

What about setting TTL in vcl_fetch

Like,

                        set obj.http.Cache-Control = "max-age=432000";
                        set obj.ttl = 5d;

Thanks,
Mahesh.

Hi Mahesh

obj.* is called beresp.* in vcl_fetch in Varnish 2.1.
