I enabled the extra debugging on a test-instance, like you proposed. obj.ttl seems to be zero indeed, but I still don't get how his would make the request cacheable. At least it's not the behaviour one would expect? Secondly: I also thought that Varnish never caches requests with a Set-cookie header? Or is it just the header that causes problems with intermediate proxies between our server and the users (and/or browser cache of the clients)?
